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.

Due to online research, I was led to ETrailer for the correct size for my HF trailer. ( I had purchased some from the chain auto parts and they were too small.) Even though I don’t dunk the trailer in water I went with the SS set. Fit perfectly. Have not had a chance to add more grease through them as the trailer sees minimal use, thus 4 stars. I am very satisfied with them, the price, and knowledge of the staff that led me to the correct size. Highly recommend ETrailer and the Bearing Buddies. 568634

This is the only way you should haul your boat trailer around if in and out of the water.The bearings are under constant pressure keeping out water and lubing also. This is the 3nd set I have bought and have them on all my trailers. I stated years ago and I have never had any issues sense I started using the Bearing Buddy. Pays for it self over and over again. The longer you have the trailer with the Bearing Buddy the more time and money you save! 645350

I bought my trailer from another store with the regular bearing caps on the hubs. I bought the bearing buddies from them later and they did not fit. After a little research I found out that what I needed was .2047inch and what I had bought earlier was 1.98inch. Etrailer has several sizes, .2047inch fit perfect. Got them in the mail in 3 days. 519184

used them all last year going to the lake 3 or 4 times a month and putting the boat in and out of the water and have had no problem. Theyve kept the water out of the bearings of my Harbor Freight trailer.

I use bearing buddies on all my trailers and highly recommend them especially for boat trailers that go under water regularly. Buying from etrailer was a little more expensive than the big box store, but I was impressed that they called the manufacturer of my Trailer to be sure they sold me the correct size. Imagine: an online company that cares enough to check ahead of time! etrailer earned my business. 400084

Great addition to any trailer used in wet, sloppy conditions. Not just boat trailers. I added a pair to an ATV trailer that is used in very muddy terrain. Very easy to install, but care should be taken to be sure you select the correct size as there are a number of sizes that are very close together. I suggest removing the old grease cap and measuring the inside diameter with a caliper. Also the addition of bearing buddies makes checking the amount of grease and refilling your hubs much easier to do. The Stainless variety are a couple bucks more but worth every penny. Would Highly recommend to anyone. 396604

I ordered these for my Harbor Freight trailer because the covers and grease they put from the factory are lacking. These have worked great so far for me. The only issue I had was actually getting them put on because it is a VERY tight fit and they have to be aligned perfectly. I suggest having a mallet you can use to tap them in. Other than that they are great! 374639

Couldn't find these in stock anywhere else. Ordered them because they are the ones that are supposed to fit my Harbor Freight Tag Along trailer which I pull behind my GL1800 Goldwing.

After much searching, I finally found the correct size bearing protectors for an older Harbor Freight trailer. I had been searching for a metric size and the BB2047SS protectors fit great! The 2.047" size is exact and with the stainless steel material, the size has to be exact, the stainless does not give. These protectors will probably outlast my trailer. The rubber caps are a nice addition to keep dirt off of the grease fitting. Overall, very impressed. Will be purchasing a set of these for my other twin axle trailer. 347476


Comments

These bearing protectors are working out great, probably have 20 trips to the mountains hauling equipment 230 miles round trip and they are holding up great. Surprisingly the rubber dust caps have also stayed on and held up in severe weather conditions with both heat and snow. Bearings and seal were also replaced and are all holding up well now that the grease stays where its supposed to. Overall, a great product!

  • Which Bearing Buddy Fits the Detail K2 Mighty Multi A-Frame Utility Trailer # K2MMT5X7
  • I had the Detail K2 Mighty Multi A-Frame Utility Trailer # K2MMT5X7 pulled from our warehouse and used the Digital Caliper # 301-17068 to find that the hub bore measured 2.041". Although it is slightly larger than the hub bore, I was able to find that the Bearing Buddy that fits a 2.047" hub bore will fit perfectly on the trailer. This size Bearing Buddy comes in Chrome Plated # BB2047 or Stainless Steel # BB2047SS. I have attached some review videos of the Bearing Buddy options for...

  • Replacement Dust Cap or Grease Cap for Trailer
  • We do have replacement dust caps. You will simply need to use a digital caliper like # PTW80157 to determine the size needed. I've linked the page to all your options to assist. I've also linked the page to the bearing protectors that have the integrated grease zerk to maintain them.

  • Recommended Bearing Buddy for 2 Inch Hub Bore
  • We have a few Bearing Buddy Bearing Protectors available that are designed to fit a hub bore of around 2 inches in diameter, but not one that measures 2 inches exactly. I recommend using a digital caliper like # PTW80157 so you can take an exact measurement of your existing hub bore. For example, the Bearing Buddy Bearing Protectors # BB1980A-SS are designed for 1.980 inch diameter hub bores while the Bearing Buddy Protectors # BB2047SS are compatible with hub bores that have a diameter...

  • Bearing Buddy Grease Caps for Hub Bore Dimension of 2.05-Inches
  • Bearing Buddy bearing protector grease caps are made in many sizes and we carry those most often used in recreational trailering. You can see all Bearing Buddy parts we have by clicking on the page I linked for you. Bearing Buddy grease caps are made both with and without threads so you'll want to check your hub bore to see if it is threaded or not. Click on the appropriate type on the page. For a dimension of 2.05-inches you can use a Bearing Buddy kit in size 2.047-inches, such...

  • Dimensions of Bearing Buddy Bearing Protectors # BB2047
  • The Bearing Buddies # BB2047SS are the only grease caps we have for the 2.047 inch hub bore. They also are available in Chrome plated # BB2047. Either Bearing buddy measures 1.776 inches from edge to edge and 1.483 on the outside of the hub without the rubber bra. I reached out to the manufacturer to confirm these measurements.

  • Bearing Buddy Sizes Compatible for Hub 2 Inch Inner Diameter
  • There are a couple of sizes close to your 2 inch diameter. If you measured with a digital caliper that goes to the thousandths like # 301-17068 then that will be much easier to determine the fit. We have the 2.047 inch # BB2047 in chrome plated or # BB2047SS in stainless steel. We also have the 2.080 inch # BB2080 in chrome of # BB2080SS in stainless steel. If it is smaller we have the 1.80 inch # BB1980A-SS in stainless steel. The fit should be snug to prevent leaks...

  • What Size Bearing Buddies Will Fit a Harbor Freight Trailer 94564
  • I actually called Harbor Freight about your trailer to determine what size dust cap is used on that trailer. I reached a tech and he stated that the dust cap is 52mm or 2.0488 inches. It looks like the best option is # BB2047 or # BB2047SS . However, you normally want them to be slightly larger than the hub bore to fit snugly. One thousandth of an inch may not be an issue but you need to be aware that it is not exact.

  • Replacement Bearings and Axle Parts for Imported Utility Trailer
  • You have discovered the dark side of "bargain" import trailers: non-standard and tough-to-find replacement parts. You are correct that the nearest diameter size of Bearing Buddy to your 2.040-inch measurement is the 2.047-inch size like # BB2047 (in chrome finish) and # BB2047SS (in stainless steel). I also checked our standard grease caps, shown on the linked page, and these too do not offer a perfect match to your hub bore. A difference of 7/1000ths of an inch in diameter is a...

  • Replacement Grease Caps for a Trailer Hub with 2-1/16 Inch Hub Bore
  • Instead of measuring the grease cap, measure the hub bore where the grease cap fits. You will need the most accurate measurement as possible so use dial calipers. You may find that you have a 2.047 inch bore so you could use bearing protectors like # BB2047SS. Or it could slightly larger, 2.080 like # BB2080. These are the 2 most likely sizes if you are coming up with 2-1/16 inches but measuring the hub bore with dial calipers would be the way to go.

  • Grease Cap Recommendation for a Harbor Freight Trailer 90154
  • The 2.09 grease cap that you tried might be the one to use. They are supposed to be a tight fit and require being tapped in with a hammer and a flat piece of wood like a 2x4. There is a Bearing Buddy that fits right between the two sizes you have tried though. The part # BB2047SS has an outer diameter of 2.047 inches.

  • Finding The Right Size Bearing Buddy For Utility Trailer
  • You'll need to use an accurate measuring device like a digital caliper to measure the inside diameter of the hub bore. A ruler or tape measure wouldn't be accurate enough. I have attached a photo of a hub that shows where the measurement should be taken. If you measure and find the opening to be 1.98 inches then the Bearing Buddy I recommend is part # BB1980A-SS. If you find that the inside hub bore measures 2.047 inches, part # BB2047SS would work well for you. If you find that...

  • Which Bearing Buddy Size Will Fit A 1.984 Hub Bore

The next closest size I would have in a Bearing Buddy is the Bearing Buddy Bearing Protectors, part # BB1980A-SS. If you can pull your wheel bearings and get the bearing part numbers that would help you with which Bearing Buddy to use. The part # BB1980A-SS works with outer bearing models L44640, L44643, and L44649. The Bearing Buddy pages also have listings...

  • Bearing Buddy Compatibility with Harbor Freight Trailer 62648

If you measure your hub on the inside of the grease cap with a digital caliper like # PTW80157, I will gladly help you find the correct Bearing Buddy if we have one compatible. You will need to remove the grease cap and either measure the inside of the hub or you can measure the outside edge of the grease cap behind the ridge where it inserts into the hub. The diameter...

  • Recommendation for a Bearing Buddy for a 2.044 Inch Trailer Hub Bore Diameter
  • For a hub bore of 2.044 inches, you will need a Bearing Buddy that is slightly larger, like # BB2047, that you have referenced. You can also use Stainless Steel model # BB2047SS. The slightly larger size will ensure a tight fit and prevent the Bearing Buddies from coming off while traveling. I have included a video that, in part, shows our installer installing a grease cap starting at about the 3 minute, 11 second mark. He goes over some of the various methods of securing them into the...

  • 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...

  • Recommended Bearing Buddy Bearing Protectors
  • You are correct. The next size up for the Bearing Buddy Bearing Protectors is 2.047 inch. To order a pair you will need part # BB2047. If you want the stainless steel protectors, you will need to order part # BB2047SS. I recommend using digital calipers to measure the inside bore of your hub to make sure the # BB2047 will work for you.

  • Why Wouldn't a Trailer Come Equipped with Bearing Buddies
  • Some axles have EZ lube spindles which means they have a grease fitting mounted at the end of the spindle already. In those cases you would not want a Bearing Buddy. Since the EZ lube spindles are more common than non-EZ lube spindles the Bearing Buddies aren't seen as frequently as you would think. Aside from that they are a great product. We only warn people to try and be careful not to over fill the hubs with grease as that can be pretty easy to do. This causes the seal to blow out.

  • Difference Between Bearing Buddy 2047 and 2047SS

  • What Bearing Buddy Will Fit Trailer Hub Assembly # 8-258BTUC1
  • I went out to the warehouse and did a test fit between the hub, # 8-258BTUC1, and Bearing Buddies, # BB1980A. The Bearing Buddies, though they are 6 thousandths of an inch smaller, will still fit tight in the hub bore. Bearing Buddies have to be driven in by putting something like a block of wood on the top and hitting the wood with a hammer. The wood disperses the energy from the hammer more evenly.

  • How to Choose the Correct Bearing Buddies for 1961 Shasta Trailer

  • Why A Bearing Buddy Is Not Recommended On A 1986 Dodge Ram D100
  • The Bearing Buddy bearing protectors are designed for use on boat trailers. On boat trailers, when the trailer is submerged into water the sudden cooling of the bearings causes a vacuum that will try to suck water into the bearing area. This water will break down the grease and also contaminate the grease with dirt, which will cause corrosion and pitting on the bearings of your trailer axle. The Bearing Buddy bearing protectors will fill the axle hub with grease which will keep a slight...
