Bearing Buddy Operation

Replace your existing grease cap with a Bearing Buddy to ensure a safe, easy way to monitor and control the level of grease in your axle hub. To adjust the amount of grease in the hub, use a grease gun to add more through the appropriate fitting. Adding grease moves the Bearing Buddy spring-loaded piston outward 1/8".

The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The interior of the Bearing Buddy is pressurized, preventing water from entering the barrel and diluting the grease.

An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This prevents overfilling that can damage the inner seal.

You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

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.

Sorry to hear that! We do offer replacement covers as part # BB23B
Replacement Bearing Buddy Bras - Model 23B - (Pair)
$2.98
. Heres a little trick to keep the covers in place. Make sure the outside of the bearing buddy and the inside of the cover are perfectly clean and free of grease, then spray a quick shot of aerosol hair spray on one side of the bearing buddy. Install the cover, and rotate it on the bearing buddy by about 1/4 turn. When the hair spray dries, itll act like an adhesive but because you havent coated the whole thing, youll be able to remove it when needed.

While we only just received out bearing buddies. They are as described and installed easily. The only trouble was the beauty covers don't fit over the hubs any longer. Doesn't really matter as the product is attractive. The wheel studs not so much but we can live with that. I will have to write another review after we have taken a few trips and greased things up a bit. 405126

I recently upgraded to electric over hydraulic disk brakes from the hydraulic drum surge brakes that were on my boat trailer when I bought it. I scoured the web site and put together a list of parts for the conversion but still had a few questions. Lisa was most helpful and had some additional suggestions. She made my etrailer.com shopping experience the best online shopping experience ever. Once I had the brake parts I found my old Bearing Buddies didn't fit the new hubs so I ordered new Bearing Buddies and new coupler while I was at it. I ordered them on Sat. and they arrived today, Tuesday. I already have the new parts on and they are working perfectly. Thanks etrailer.com and thanks Lisa. You have a new customer for life. 372263

Bearing Buddies are worth the investment. Saves time on maintenance and money on parts (and labor if you farm out the work). I've used these on flatbeds, cheap Harbor Freight trailers, utility trailers and now finally putting them on my toy hauler. Quality piece and is US Made. The ONLY suggestions is verify your hub size and if you measure it and still doubt what you measured ask etrailers wonderful customer service. there are a lot of different hub sizes. Josh D 352981

Do you have a question about this Trailer Bearings Races Seals Cap?


  • How to Determine Correct Bearing Buddy for Trailer
  • It is really easy to determine which Bearing Buddies are the correct fit for your trailer, though we have no way to confirm a fit on any specific make or model, though I do appreciate the detailed info. For you to confirm the right Bearing Buddies all you need to do is measure the hub bores on your trailer's hubs using Digital Caliper # PTW80157 and match the hub bore diameter to the correct Bearing Buddies. Or if you let me know the outer bearing I can match its race, which will have the...

  • It is really easy to determine which Bearing Buddies are the correct fit for your trailer, though we have no way to confirm a fit on any specific make or model. For you to confirm the right Bearing Buddies all you need to do is measure the hub bores on your trailer's hubs using Digital Caliper # PTW80157 and match the hub bore diameter to the correct Bearing Buddies.

  • Bearing Buddy for 2.447 Inch Hub Bore
  • The Bearing Buddy Bearing Protectors # BB2441 referenced in your question are compatible with 2.441 inch hub bores. We do not currently have Bearing Buddies that fit the exact 2.447 inch dimension that you referenced, however this will be the closest option. I recommend verifying the size of your existing hub bore with a digital caliper like # PTW80157. Another option is to wipe away the grease on your hub to see if you can locate the outer bearing number, which will also help to identify...

  • Bearing Buddy Recommendation for 5,200 lb Axle Kodiak Rotor Hub
  • The correct bearing buddy for the Hub part # KHR12D that you referenced would be based on the 15123 outer bearing that the hub uses. Based on that you would want the Bearing Buddy part # BB2441. Installing the Bearing Buddy is pretty easy and would not work with the tool you mentioned. I have included a link to a video and if you fast forward to about the 5:20 minute mark, our installer puts one on. He lines it up first and gives it a tap to get started. Then he places a block of wood...

  • Recommended Grease/Dust Caps for the Kodiak Disc Brake Kit # K2HR526D
  • The correct grease/dust cap size for your Kodiak Disc Brake Kit # K2HR526D is 2.44". For EZ Lube grease caps with this dimension we have part # RG04-080 which comes in a quantity of 2. If you are wanting to upgrade to Bearing Buddys (which would require you to remove the grease zerk on your spindle) we have these both in Chrome # BB2441 and Stainless Steel # BB2441SS. The advantage of the Bearing Buddys over the EZ Lube is that the Bearing Buddys give you an easy way to add grease and...

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
  • Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • How to Pick Out Bearing Buddy to fit Trailer Hub
  • The way to pick out Bearing Buddies for a trailer hub is based on the diameter of the bore of the hub where the grease cap fits. If you have 2-1/2 inches you most likely would need the # BB2562 which fits a hub bore of 2.562 inches or the # BB2441 which fits a hub bore of 2.441 inches. Since the measurement needs to be exact you'll want to use a caliper like the # PTW80157.

  • Diameter of the Grease Cap for the Dexter Trailer Hubs and Drums # 8-174-5UC3
  • The replacement grease cap for the Dexter Trailer Hubs and Drums # 8-174-5UC3 that you referenced is the Grease Cap part # RG04-060. This cap has a flange diameter of 2.446". For a tool to drive this cap on you would want the part # 290-992. If you were looking for Bearing Buddies for this hub you would want part # BB2441.

  • Do Trailer Hub Bearing Buddies Also Work with Inner Bearings
  • A Bearing Buddy allows you to pump grease into the center of the hub all the way back to the grease seal. A double lip seal should be used to prevent grease from blowing out the seal when added. You can pre-pack the bearings if you wanted to but that would negate the function of the Bearing Buddy. The outer bearing is mentioned because that is how the hub bore size is determined.

  • Bearing Buddy Recommendation for a Dexter Hub part # 8-201

  • What Size Bearing Buddy to Replace 2-7/16-Inch Grease Cap
  • The best way to measure hub bore to determine which Bearing Buddy size you need is with a digital caliper. If you do not own one you may be able to borrow or rent one from a local auto parts store. Your other option is to obtain the outer bearing number from your trailer. You may be able to obtain the bearing number without having to pull it from the spindle; try wiping it clean of grease to see if the bearing number can be read. The size you quoted, 2-7/16 inches, corresponds to...

  • Bearing Buddy for 5.2K Trailer Hub and Drum Assembly with 6 on 5-1/2 Bolt Pattern
  • Yes, for trailer hub and drum assembly # 8-201-5UC3 you can use Bearing Buddy # BB2441. There is also a stainless steel model, # BB2441SS, which is great for marine applications.

  • Bearing Buddy Recommendation for the Trailer Hub Assembly # 8-213-5UC1
  • The grease cap included in this hub kit # 8-213-5UC1 has an outer diameter of 2.44-inches. So the correct Bearing Buddy would be part # BB2441 or if you want the stainless steel version that will resist corrosion much better you would want the # BB2441SS instead.

  • How to Determine the Right Bearing Buddy Bearing Protector for 2-3/8 Inch Hub Bore
  • To choose the correct bearing protectors, if available, you will have to measure the hub opening using dial or digital calipers because the measurement has to be as exact as possible. Bearing protectors are measured to the thousandth of an inch (3 decimal places). None of the bearing protectors we carry are exactly 2-3/8 inches (2.375 inches) but # BB2328 and # BB2328SS are the closest at 2.328 inches. The next step up, # BB2441, at 2.441 inches would likely be too big if the measurement...

  • Bearing Buddies for Dexter Axels with 6 Lugs on My Fifth Wheel Trailer
  • You will most likely need the Bearing Buddy Model 2441 for your trailer with Dexter axles. You should measure to be sure, before ordering. The outside diameter of the original drive in grease cap seating surface should be 2.44 inches. If your grease cap is too damaged to get an accurate measurement then you can measure the inside diameter of the cap seating surface on the hub which should also be 2.44 inches. If your grease cap measurement is different let me know and we will get the...

  • Which Bearing Buddies Will Fit a 2-7/16 Inch Hub Bore
  • You will likely need 2441 model Bearing Buddies: # BB2441 for chrome or # BB2441SS for stainless steel. Your hub bore will be slightly less than this if it is exactly 2-7/16 inches and that ensures a tight fit. The hub bore should really be measured using calipers such as # PTW80157 because the measurement has to be as accurate as possible.

  • How to Pick out Bearing Buddies
  • In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening. I have included a video demonstrating the Bearing Buddy. The Bearing Buddies # BB2441 that you referenced are for hubs with a 2.441 inch hub bore. I...

  • When Using Bearing Buddy Bearing Protectors Do I Need To Repack Bearings Periodically?
  • When you use the Bearing Buddy Bearing Protectors like # BB2441, so you do not need to take apart the wheel hub and repack the bearings. The Bearing Buddy Protectors have a spring loaded seal that keeps the moisture and debris out of the bearings. This pressurized grease will maintain bearing function as long as the seal on the hub stays functional. If this seal is broken, I recommend inspecting and repacking good bearings when you replace the seal. As you maintain the grease in the...

  • Can Air Escape Trailer Hub Seals When Filling with Grease with Bearing Buddy
  • Grease seals are not air tight so the air would be able to escape as you fill the hub up. They are tight enough to keep the grease in though. Grease does breakdown over time so you do occasionally need to add more. The grease seals are also not totally sealed. They do a pretty good job sealing but in general contaminants can still find there ways in.

  • Determining Size of Bearing Protector Needed for 2001 Load Rite Trailer
  • The best way to determine the size of bearing buddy needed would be to take a highly accurate measurement of your hub bore using a digital caliper. I have edited a photo for you that shows this dimension. If you happened to know the reference number from your outer wheel bearings, the proper bearing protector could be determined. If you would care to reply with either the hub bore dimension or the outer bearing number, I would be happy to suggest a bearing protector for you.

  • How to Remove Bearing Buddy Trailer Bearing Protectors

  • Does Grease Seal have to Make Contact with the Inner Race for Bearing to Ride in the Right Place
  • A hub should only have one grease seal, at the back side of the hub, and it should be flush with the hub once installed. When everything is assembled and put on the spindle with the castle nut properly tightened down there should be only a few thousands of an inch of play meaning everything is in place. Races are pressed into a hub so they are not going to move and the edge of the grease seal may or may not make contact with the inner race. But that contact or lack of contact should...

  • Installing Bearing Buddy Bra # BB23B
  • As a first step, make sure you are using the correct Bearing Buddy Bra for your application. The # BB23B you mentioned is sized to fit Bearing Buddies that fit hub bores ranging from 2.240 inches to 2.562 inches, or model #s BB2328, BB2328SS, BB2441, BB2441SS, BB2717, BB2717SS, BB2562, BB2562SS, BB2240 and BB2240SS. Applying a very very small bit of grease (I am talking tiny) to the outside of the Bearing Buddy will allow the bra to slide on easier. While sliding the bra into place,...

  • Bearing Buddies Recommendation for a Dexter P-11 6 hole axle 6K Axle
  • In order to determine which bearing buddies you need, you are going to need to remove the hubs of your trailer and get the number off of the outer bearings. Most 6K axles have outer bearing numbers of LM-67048, 15123, LM-67010 or 15245 which all will work with the Bearing Buddy Bearing Protectors # BB2441 that you referenced.
