Video Transcript for Trailer Bearings Races Seals and Caps Rebuild

Speaker 1: Today we're going to take you through the rebuild process on a couple of hubs. We've got an idler hub, and here we've got a hub and drum assembly. Works with electric rigs, but this can also work for just standard discs, if you've got a disc brake style setup.Basically what we're going to show you is how to get all of the bearings out. How to remove the seal. How to remove the race's if they're damaged, then get them replaced in the proper manner. We'll show you how to use an easy loop hub, which we have here.The first thing we are going to need to do is, get the grease cap off the end.

It can have either a rubber plug in it like this one does, or it can be a solid metal cap.These are pressed fit in there, basically by tapping on them on the back side. To remove them, a deadbolt hammer is typically what we're going to use. We're just going to start tapping as we go around. You'll see a little separation start right here, and slowly it'll work it's way off.Now the next step's going to vary a little bit depending on your axle setup. Do you see this is going to have a keeper that goes around the nut.

And that prevents that from being backed off, or removed. A lot of times you'll have a castle nut, which will have just little tabs that stick off, and there will be a cotter pin that passes through it. Just depending on your application, you need to get the keeper for the nut off. This style we just kind of pry out. A cotter pin you would just remove of course.Once we have that off ...

We'll start to take off the nut here, and the washer that's in behind it. Now yours should look a whole lot more dirty than this. There should be a lot of grease packed in, and through the hub, this one's brand new. We thought it'd be nice to show you the components before the grease was on .. Of our washer that comes off.And then here we're going to have our outer bearing.

Continue to pull that. We're gonig to have our inner bearing here. That sits in the backside of the hub. And we didn't put it in yet, we will show you how to put it in. But a seal would typically be covering the backside here. We'll show you how to use a seal removal tool, or another tool. To get that pried up and out. To get an access to that inner bearing.Now for a drum style like this, that process for disassembly is going to be just the same. One thing to keep in mind if you're using a disc brake setup. You'll have to remove the caliper before the disc is going to come off.Now once we have the spindle exposed, as we said this is going to be really greasy. We want to get all the grease removed, and the first thing we'll do is inspect it. We want to make sure that it looks just like what we have here. Everything's nice and smooth. We don't see any kind of discoloration, or any marring on the metal. Indicating that our bearing's got hot.If you do have any of those symptoms, at this point it's time to replace those bearings. You don't want to repack them. Get new bearings, and put in there. You might have a bearing that's come apart in here. Another surface to ensure is in good condition, is where your seal is going to go. That helps seal all the grease inside of our hub. With a damaged or broken seal, that grease is going to seep out. Either out of the hub, or in this case into our brake assembly.Now if your axle has brakes, we're also going to check the disc. Make sure it doesn't have any issues, or your hub. And this is going to be a hub and drum assembly. The brakes are going to ride on this machine surface. You're going to check that for signs of excessive heat, discoloration, or cracking. And this is our magnet surface. We'll check that surface for the same issues.Now inside the hub regardless if it's a disc brake, it's a drum brake like this. Or just a standard idler style hub. You're going to have an outer race. Would be right here, it's a small tapered piece of metal your bearing sits in, and rotates on. That's basically the outer portion of the bearing.You have the same thing here on the backside. This is called the inner race. Now if those show any signs of wear, overheating, or cracking. Those are also something we'll need to replace, which we'll show you how to do in just a minute.Now, with your brake assembly exposed, if you do have electric brakes like we have here. It's a good idea to check all the components for wear, cracking, maybe missing pieces. Check your pad thickness to make sure those are in good shape. Basically if you have a non working brake assembly and you put everything back together, you're just going to have to take it apart and do it all over again to get back to the brake assembly. This gives you a really good option to be able to change them out.And most applications are going to use a four, or maybe a five bolt flange to hold them in place. And you'll just remove the lock nuts, or sometimes you'll have a hex nut with a lock washer. You want to remove those, and then simply slide your assembly off after you cut the wiring.The friction material itself should also be checked for any kinds of cracking, or overheating. If you have any grease inside the system at all, it's likely it's gotten on those pads. It's a good idea to get those changed. Now as far as the removal of the races go, it's going to be just the same whether we're using an idler style hub like we have here. A drum brake like we have here. You can basically see where the idler is, here in the middle of the hub. It's going to go all the way around there, and we just have this extra material here to provide our braking surface.Now if you're doing a disc brake style job again, it's going to be just the same here with the races living inside of the actual hub portion. You'll just have the discs there for the brakes to make contact. We're going to use this little bit smaller one, it's a little bit easier to manage to show you how to get these out. We've talked about where the races are. The outer here, the inner being closer to the inside, but on the backside of the race there's a little lip. That lip's meant to stick out just a little bit further than the hub, and provide us an area to put our tool on, and help to drive that out.If you look all the way through there on that inner race, you'll see that little lip that sticks out just from the hub slightly, and it gives us enough area to use our tool on. Now generally to remove these you're going to use a punch, similar to this. Some guys will use a screwdriver. Or a piece of pipe. If you have a piece of pipe that's small enough to fit inside of that diameter, you can take that down through and allow it to rest on that lip.Use our punch, and then just need a hammer. And we'll start working that out. We're going to tap all the way around. Kind of equally, and evenly apply the force to get it to come on out of the bottom for us.You can see now as it starts to come out there's going to be a little gap created between the hub and the race. And we can just keep going, bringing it on out. Then you can inspect the inside of the hub surface there. Make sure no damage or anything has occurred, and repeat that same process for the outer race if you plan on removing and replacing that one.Now in the outer flat edge, you can see we're going to have our tapered edge on this side. If we roll our race over to the flat side, typically there's going to be a manufacturers part number on there. That will help you identify which race it is, that you need to go back in your system. If those are rubbed off, worn off, if you can't read them. You can measure the outside, to outside diameter of the race here. It's a good idea to use a micrometer to get it exact.Now here's your basic micrometer. And again, the outside of the race is what we're going to need to measure. You want to go . I set the thickest point there. Looks like this one's going to be about 1.98. That's going to be the measurement you'll want to supply.Now while we've got this out, let's also look at the proper way to measure our bearing. Instead of the outside for the bearing, we need to measure the inside diameter. That's going to be pretty simple. Let's pull that out, find the largest measurement we can. Which here, looks like it's going to be 1.03. With that information, we'll be able to get the correct bearing, and the correct race, so they'll fit together properly and make a full bearing kit for us.Now here's the race, we're going to show you how to get this put back in. Basically just going to press fit inside of our hubs. We need to get it down on there. Kind of like that. And you'll have a couple options. A lot of times you're going to see do it yourself or at homer, just going to use a wooden block. Just place it on there. That's going to get you started, but at that point you'll struggle in getting it to go all the way down into it's seat.Now to take care of that problem, there are several seal drivers that are available. Seal and race drivers that are available out there on the market. It's designed to fit down inside of our race, inside of our hub and get it down there where it needs to go. This is part number ptw83020, has several different sizes, even if you have multiple trailers it's going to do the job.Now the side with the angle on it, is designed to fit down inside of our race. If we use the other side, that's going to be for driving your seal into place. Just want to hold it, and take it on in with your hammer. You'll see, you just want to insure that our race is all the way up against that line on the hub where it's supposed to mate to.Now when it comes time to pack your bearings you're going to have several different ways of doing this. You can just use your hand, is the traditional method. That's going to be the method probably reserved for the very occasional trailer work kind of situation. If you do it once or twice a year, probably get away with it that way.Next you would go to a, kind of a sandwich funnel style almost. If you look inside of there, you can see the bearing. It's located between the two pieces. Just use a grease gun. Start filling that with grease, and that's going to fill our bearing for us. And the third, with this one you're just going to place your bearing down and in. It should be pretty close to center. And then we've got our cone her that's going to go down and secure that.Now I think this style, wastes a little bit more grease than what this style will. This has a dust cap. You can see, you can keep your grease in there, put your dust cap on there and save it for later use. This will be if your going to do it every couple years. And this particular style would be if you're a more regular user.Let's start by showing you how to use a bearing packer. Similar to this. Again, we've just got our grease inaudible 00:11:07 here on the top. And then just slowly start to fill it. Now I like this style quite a bit. I think even regular users might enjoy it, because you can get a really quick visual look at that bearing. You're not going to have to overdo it, or have to much grease.You can kind of see in there now, we're starting to get grease to come out of it. Couple more pumps, we'll be good. You can see we've got grease coming out all the way around. Where all of our bearings are. Got a little bit of excess there. Just take that around the outside of it. And then we should be able to lift it off. And now you can see what we we're talking about. Just a little bit of excess there, that you're just going to wind up wasting.Now we'll take our bearing, we're going to place it right down in our race. And then we'll cap off the back with our seal. Right now our seal's going to fit in just like our race did. It's going to have a little bit of a pressure fit to it. Now very often in this situation, I see people using the four by four method. Kind of here, just placing that on and tapping it. As an option though, if you do have one of these. You can see that's designed to fit right on the top of the seal. And help drive it in.The biggest thing here is, just going to be getting it driven in squarely. You can see, this side's in a little bit further than this side. I'm going to start this side first. Now since we didn't have the opportunity to show you before, we're going to take a look at pulling a seal. Now this is a seal puller, we carry this on our website part number ptw1219. This is meant to hook underneath the seal. And then you kind of pull up on it, and just like our race you'll have to work all the way around that edge. Just bringing it out a little at a time.If you don't have that available. Another option would be a screwdriver. You just kind of get that under the seal, and turn it. And see, that'll allow you to also pop that out. We've taken care of our race. Our inner bearing. Our seal. The last component, before we put our hub back in place is going to be our outer bearing. Now with this bearing, I'll show you the hand packing method.This is definitely . Slightly dirtier method than the bearing packer. When we get grease on our hand we want to look at the larger side of the bearing. This is the smaller side. We have a larger side In between the inside and outside there's a gap. We can see our rollers in there. We want to grab that, and use that gap and shove grease inside of it. Now this is going to take a little bit, you want to work in the same spot until you get the grease pushed all the way through. We can see on the top there we've got a little bit starting to come through.And once we push it in the bottom, and you see it start coming out the of the top in those little drips, it's going to indicate that, that section's fully packed. Just need to work all the way around their outside edge now and do the same thing. Alright, once that's all the way around . The bearing will be ready for use.Now one more thing I like to do. We can see our inner bearing there, and our outer bearing. Well between the two, got a pretty big gap in there. If you'll take a . Pretty good amount of grease. We're just going to go all the way around. See how we can go all the way around the inside and just line that really well. The more grease we have in here, the less chance we have of any moisture getting in there, which can cause corrosion, rust, pitting. Pretty much things we do not like when it comes to bearings, races, and hubs.Put plenty of grease in there. And then this one does have the easy lube spindle, that'll even fill it in more. Now we can get our assembly slid on. I like to keep my thumbs on that outer bearing, just to prevent it from . inaudible 00:15:28 pushed off there. Now we can put on the original hardware that we removed, in taking off our hub the first time. In our case, we had our washer and our nut.Now most commonly you'll see pliers similar to this being used. We basically want to get that tightened down. Once it's fully tightened down you'll feel some resistance in the hub. We back it off just slightly. That'll give us a little bit more freedom of motion there. Something you don't want however . Is any movement in, or out on your hub. You want to be sure that everything is compressed, and you don't have what's called end play. Which would be the play in and out.Once we've got that set, then you'll put on whatever tight keeper yours came with. Get that put back in place. Now with an easy lube style hub, you're going to place your grease gun on the end, and then you can just fill the remainder of that hub up.Now for your typical applications, you're either going to have a solid cap, or a cap that'll have a rubber plug in it. A solid cap's going to be for an axle without the grease inaudible 00:16:51 here on the end. Goes on there. Just knock it on with your rubber mallet. Same with the one with the plug. Just gives you a removable area there, be able to cap that off.We'll show you how to put that on. Now as alternatives as well, a lot of times on boat trailers and marine kind of situations. You'll see a bearing buddy. This is going to apply a little bit of pressure on the grease, you'll fill it up. This kind of comes out just a little bit. That applies constant pressure on the grease to make sure we don't have any air, or anything like that. Then there is also an oil bath hub available. Now this is going to be for use with seals that are going to be designed specifically for oil bath use. You'll have to change that seal.We're using a double lip seal. There are also single lip seals available. Of course a double lip seal is going to give you just a little additional security. Keep that in mind when you order. But let's get this knocked on there now so you can see how that works. We just want to take the cap, we're going to center it. This is going to be very similar to what we did with the seal. And then just gently start tapping it around the outside. And it'll seep down on there for you.It's really going to be the same thing that you'll do with any of the end caps. Now with this side done, it's a good idea to take care of all the other hubs. Get them all on the same maintenance schedule. And as long as you'll periodically check the grease, take your trailer out for a trip occasionally. Just to keep everything lubricated. It should extend the life of these parts, and give us years of good service.

I'm very pleased. The item was shipped and received quickly, and the diameter of the dust caps' diameters measured exactly what they were nominally listed as (1.98"). They were also cheaper with etrailer than anyplace else, in my online search. 258702


Comments

I ordered the wrong size. I just tried to install them, and found that the bore is substantially larger. I have a Haul Master trailer from Harbor Freight. Do you have the right grease caps?

Steve M - 06/07/2017

Thanks for the response, unfortunately we can not cross reference the grease cap you would need based on trailer manufacturer. But to determine the correct size you would need to measure the inside diameter of the hub opening to determine which cap size is needed, preferably with a precise measuring device like dial calipers. You would want to choose a cap with an outside diameter that matches the inside diameter of the hub.

I replaced all the bearings races seals and brakes on a small travel trailer. Bill P.at etrailer took my order and three days later I had everything in my hands. Great job Bill ! All the parts were exact replacements and the install went very smooth. There is video help on their website to show how to make the install easier. I have been dealing with etrailer for several years and have never had a bad experience. I was completely blown away by the pre assembled brakes . Backing plate, shoes, actuators, self adjusters and wiring all ready to bolt on. How much easier can it be? With the best prices, fast shipping and great help on line etrailer is the way to go. 293852

Replaced the existing caps that had access to the grease fittings with a rubber grommet for a cover. I don't think greasing the bearings from the end of the axle is the way to go. I took some steel wool and roughed up the outside and painted them with black paint to match the hub. 457864

  • Replacement Grease Cap for Malone MegaSport Kayak Trailer 86" Crossbars 14' Long 1000 lbs MPG535
  • We have a Malone MegaSport Kayak Trailer - 86" Crossbars - 14' Long - 1000 lbs Item # MPG535 that we use for demos so I went out and measured the grease cap to determine the correct size needed. It takes a 1.98 inch standard grease cap. For a single use # F001518. For a pair use # RG04-020.

  • Finding Replacement Bearing Sizes for 2006 EZLoader Trailer
  • I spoke with EZLoader, who gave me your bearing sizes. The inner bearing is # LM48548, which measures 1.375 inches. Its matching race is # LM48510. The outer bearing is # L44649, which measures 1.063 inches. Its matching race is # L44610. You can also purchase a grease seal set, # BB60002. We also offer grease caps for 1.98 inch hub bores, such as the standard grease cap # RG04-020, and the EZ Lube grease cap # DC200L-DCRP. I've attached several review videos of these products...

  • Will Fulton 1.96 Inch Grease Cap Fit Hub and Drum for a 3,500 Pound Trailer Axle
  • I tested a Fulton Grease Cap # F001610 in a standard 3,500 pound axle hub and drum assembly out in our warehouse. The cap just drops right in and would fall back out immediately. You will definitely need the 1.98 inch caps # RG04-020. They are about 1/4 inch (0.26 inches) taller than the Fulton caps.

  • 2.44 inch Diameter Dust Caps for Trailer Bearings on a Coromal Van
  • We carry the TruRyde Grease Cap, # F001520, that should work for you, but you will need to make sure that the depth of the cap will work with the existing hubs on your Coromal Van. The depth of this cap is 1.03 inches, so as long as the spindle on your van does not protrude more than 1 inch beyond the face of the hub this grease cap will work for you.

  • Disc Trailer Brake Kit Recommendation for a 1997 EZ Loader Boat Trailer
  • With 13 inch wheels, you will need a different set up to add disc brakes to your boat trailer. For the brakes, I recommend the Kodiak Disc Brake Kit - 10 Inch Hub/Rotor - 5 on 4-1/2 - Silver Cad, # K2HR35DS for inner bearing and race L68149 and L68111, outer bearing and race L44649 and L44610. These are designed for 13 inch wheels and the silver cad finish provides superior corrosion resistance for marine applications. Your wheels will need to have a 5 on 4-1/2 bolt pattern. The bearings...

  • Trailer Hub Bearing Kit Recommendation for 1990 Coleman Pop Up Camper L44649
  • Since your hubs have inner and outer bearing numbers L44649 the correct bearing kit you would need is the part # BK1-150. I attached a trailer bearing install video for you to check out as well. For the standard spindle you would use the TruRyde Grease Caps, # RG04-020. If you have a E-Z Lube spindle, with a grease fitting in the end of the spindle, you would use the TruRyde Grease Caps, # RG04-040.

  • Replacement Grease Cap For Nationwide Pontoon Trailer
  • I can absolutely help you with this part. It sounds like for the deep dish, you may be looking for an EZ Lube Drive-In Grease Cap, that is # 21-41-1. There are grease cap plugs for the EZ Lube # RG04-010. I reached out to Nationwide Pontoon Trailer and they let me know the size needed and these are a fit for your trailer. If you prefer the rounded metal style, your replacement bearing cover is Grease Cap # RG04-020.

  • What Size Grease Seal And Dust Cap is Needed on a 3,500 Lbs. Axle With L44649 Outer Bearing
  • The size seal you will need will depend on the part number of your inner bearing. If the outer bearing part number is L44649 and the inner bearing part number is also L44649, then you will use a TruRyde Seals, # RG06-020. If the outer bearing part number is L44649 and the inner bearing part number is L68149, then it will be TruRyde Seals, # RG06-050. The size grease cap you will need is 1.986 inches. For the standard spindle you would use the TruRyde Grease Caps, # RG04-020....

  • Bearing Kit and Dust/Grease Caps for Coleman Mesa Camper with L68149 and L44649 Hub Bearings
  • As far as bearing kits go # BK2-100 is the only one that has both the L44649 and L68149 bearings. The seal that is included is a 10-19 with an inner diameter of 1.719 inches and outer diameter of 2.565 inches. Based on my research this is the correct seal. Your hubs should have a center hole for the grease cap that is a little under 1.99 inches. Use calipers such as # PTW80157 to measure the hub bore to be certain. For a set for EZ Lube axles use # RG04-040. For a set of regular caps...

  • Purpose of Grease Caps and How to Measure to Get Correct Size
  • The purpose of the grease cap is to protect the bearing and the axle from any dirt getting into the bearing, which would then damage the bearing, hub and axle. So it is a good idea to have caps on your axle. To get the correct size cap you would need to measure the inside diameter of the cap mounting surface on your hub. Then that measurement would match up to the cap size outside diameter. The sizes of caps only vary by a small amount so the measurement has to very accurate. Some of...

  • Need a Grease Cap / Hub Dust Cap to Fit Dexter 10 Inch Drums
  • If you have a standard spindle you will use Grease Cap, # RG04-020, on your 10 inch drum. For an E-Z Lube spindle, Grease Cap, # RG04-040, would be used.

  • How to Measure a Trailer Hub or Dust Cap to Find the Right Replacement Dust Cap
  • You can measure either the outer diameter of the part of the dust cap that fits into the hub OR the inner diameter of the hub where the dust cap goes using calipers such as # PTW80157. Calipers are needed because the measurement has to be as accurate as possible. I also might be able to figure it out based on the outer bearing number which you should be able to see without taking the hub off.

  • Looking for Bearing Grease Cap that is between OD 1.99 and 2.251
  • We don't offer a grease cap with a diameter between 1.99 and 2.251 inches. The bearing reference number is stamped into the bearing cage, as shown in the photo I've provided. If I knew the bearing number, I can determine which race is used. The grease cap and the outer race will have the same outside diameter.

  • Wheel Bearings, Seals and Grease Caps for Dexter 10 Inch Trailer Hub/Drum with 8-247 Casting Number
  • The 8-247 casting number refers to a Dexter 10 inch hub/drum with a 5 on 4-1/2 inch bolt pattern. The hub/drum uses a # L68149 inner and a # L44649 outer bearing and 10-19 grease seals, part # RG06-050, sold in pairs. For grease caps, use # RG04-020 sold in pairs. If your trailer has EZ lube spindles, you'd use # RG04-040 which feature removable plugs so you can easily access the grease zerks in the end of the spindles. We don't offer a synthetic grease.

  • Replacement Grease Cap for Harbor Freight Trailer
  • Harbor freight trailers typically use metric bearings, which can make finding replacement bearings, grease seals and grease caps pretty challenging. You could very well find that you'd need to contact Harbor Freight directly. To see if anything we offer would work, use an accurate measuring tool like a digital caliper, and measure the inside diameter of the hub bore where the grease cap would insert. Click the link I've provided, and see if the diameter of any of our available grease...

  • Looking for Grease Cap With OD Slightly Larger than 1.98 Inches
  • The next largest size is # RG04-040 which has an OD of 1.99 inches. If you can provide me with the reference number from your outer wheel bearing, I'd be happy to check into the availability of a suitable grease cap.

  • Grease Cap Recommendation for Hub Bore of 1.96 inch
  • The part # RG04-020 might be barely too tight of a fit. Instead you would want the part # F001610 which is designed for fitting 1.96 bores on hubs like what you have. The overall height of this is 1.375 inches.

  • Recommended Bearing Kit With L44649 Bearings As Well As Grease Caps For Marine Application
  • I recommend you get two bearing kits # BK1-150 along with the Bearing Buddy Bearing Protectors - Model 1980T-SS - Threaded - Stainless Steel (Pair) # BB1980T-SS. These are made specifically for marine applications. If you want regular grease caps, you will want # RG04-020. These are 1.988 inch outer diameter and the closest to the measurement you gave that we carry with the exception of the Bearing Buddy Caps.

  • Converting Electric Brakes To Electric Over Hydraulic Disc Brakes On Triple Axle Trailer
  • Yes, we have the HydraStar Hydraulic Brake Line Kit - Triple Axle - 15' Long, 1/4" Main Line, # HS496-153. We also have a 30 foot long kit, # HS496-253. With either kit, I recommend use with the HydraStar Vented Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi, # HBA16. This will convert the electric system over to a hydraulic system with the electric motor that pushes the plunger into the hydraulic master cylinder as you brake. I assume you have 3500 lb axles, and...

  • How to Measure a Trailer Hub for the Correct Size Grease Cap for a 1993 Coleman Pop-up Camper
  • You would need to measure the inside diameter of the hub opening to determine which cap size is needed. You would want to choose a cap whose outside diameter matches the inside diameter of the hub. Some of the most common sizes are 1.980 inch, 1.986 inch, 2.441 inch and 2.717 inch. As you can see the sizes can differ by very small amounts. To measure accurately to two or three decimal places, I'd recommend using a digital caliper like part # PTW80157 so that you can be confident you...

  • What is the Bore Size of the Dexter Trailer Hub and Drum Assembly # 84557UC3
  • A 1.98 inch inner diameter bore is pretty common on trailer hubs. If you were to measure the bore diameter of the Dexter Trailer Hub and Drum Assembly, # 84557UC3, using a dial caliper, you would get 1.96 inches. This hub requires a grease cap with a 1.98 to 1.99 inch diameter. The grease cap that comes with this hub actually measures 1.99 inches. If you are looking for a replacement dust cover, you have many options. For a standard dust cover, you can use part # F001518 or # RG04-020....

  • How To Remove and Install Grease Caps and Bearing Protectors on Trailer Hubs
  • Grease caps just pop out and in. The best way to get them out is to pry them with a flat head screw driver or tap them from side to side with a hammer. To install new ones, you simply gently hammer them in. Normally I use a short piece of 2x4, to help tap the grease cap or bearing protector into the end of the hub. I have added links to a couple of videos that demonstrate removing the grease caps.

  • How to Pick Out Replacement Dust Caps for a Trailer that Previously Had Bearing Buddies
  • If the bore you measured on your hub measures 1.980 inches then the correct cap would be to use the RG04-020. You will need to use a more exact measuring device than a ruler though like the caliper part # PTW80157 since it has to be an exact fit. Once you have an exact dimension check out the link I attached that will take you to a page that has all of the grease caps we offer. The filters will allow you to select the correct caps.

  • Are Trailer Axle Grease Caps Waterproof
  • A grease cap like # RG04-020 is primarily intended to keep grease inside your hub bore and keep contaminants like dirt out. They are not totally water-proof by any means but they certainly do provide a degree of water-resistance. Mostly what keeps water out of your hubs is the full level of grease inside them. That is why folks like EZ-Lube spindles since they make it so much easier to ensure your hubs' grease level is always full.

  • Standard Grease/Dust Caps Won't Fit Hubs on Trailstar Boat Trailer
  • It sounds like your trailer has the stubby spindles on it that are usually associated with boat trailers. It is possible that you will need a special dust cap to fit it if there isn't enough space for a standard one (the trailer manufacturer should be able to direct you to the best option). But there is another possible solution. If you can tell me the diameter of the wheel center pilot hole I can see if center cap is available. There are Bearing Buddies, # BB2047 or # BB2047SS that...

  • Is there a Bearing Kit for L44643 Bearings that Includes Races, Pin, Dust Cap, and Seal 203025
  • The bearings we have, # L44643, and the associated race is # L44610. The cotter pin is # 165649. The dust cap associated with hubs that take these bearings is # RG04-020 for a pair. The seal on the other hand is an odd size. There isn't a bearing kit that has the seal that you need and it is an odd size that we do not carry. But it is readily available at auto parts stores. I know that a kit would make things a lot easier but in this situation there isn't a kit that has the seal and...

  • Comparing TruRyde and Fulton Grease Caps for Trailer Hubs with 1.988 Inch Bore
  • There is basically no difference between dust cap set # RG04-020 and single cap # F001518 other than # F001518 is a single unit and # RG04-020. They otherwise have the same dimensions just from two different manufacturers.

You will want to use the correct bearings and seal that are designed for that particular hub. The Dexter Trailer Hub Assembly, part # 8-91-05UC1, comes with the # L44649 inner and outer bearings, the # L44610 races, the # 10-9 grease seal, and the # RG04-020 grease cap.

  • Bearing Buddy Grease Cap for Hubs on Box Trailer
  • When you re-pack a hub with fresh wheel bearing grease you do not need to also pack grease into the interior of the standard grease cap like # RG04-020. If you packed the bearings by hand or used a packing tool like # ALL647646 the bearings themselves will have a good amount of bearing grease and there would be no way for any grease put into the grease caps to get into the bearings. This is why there are Bearing Buddy grease caps like # BB1980A-SS that have a zerk grease fitting with...
