Bearing Buddy installed diagram

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.

Great for, I didn’t realize I had the ez lube axles and didn’t need these. I really like the covers better than the cheaper ones. I removed the inner zero assembly so I can use these as caps. Much thicker material and better looking.


Bearing buddies showed up with one missing, emailed CS and they shipped out two more! Emailed back that I only needed one and to send me a RAN.
Great experience and will use etrailer for further purchases.


Bearing buddies look better than what I have


Products were just as described. Fit perfect and instructions were very helpful. Shipping was fast. Perfect transaction.


Ordered these for my 5th wheel trailer 8 days before vacation. They were shipped and received with 3 days to spare. Installation was flawless. Thanks etrailer. Well done!

Just started our camping season. Pulled the caps off, hooked up the grease gun, pumped some grease and done. Took longer to write this then grease. No pulling the 4 tires to get to the bearings and getting my hands greasy.

Your product arrived on time and undamaged. It installed exactly as described in the literature. I am very pleased with my new Bearing Buddy's. As a side note I noticed a small amount of chrome machining debris inside the hub of the housings. It was easily cleaned out with a rag before installation. These Bearing Buddy's are installed on a 32 year old utility trailer I am refurbishing. Although the trailer is small (4 x 8) it has a 5000# axle and has seen some pretty tough use. Ive attached a pic of the trailer undergoing refurbishment along with a couple of pics of the installed Bearing Buddy's. Excellent product and service!


This product is as good as their rep have used them before on a
boat trailer never had a bearing go out as long as I used the
buddy bearings they are great! Service was just as good.
These bearings were installed on a heavy duty low boy trailer.
No pictures trailer is in South Texas about 300 miles from my location. Hauling oil field equipment. Picture of the trailer being
overhauled before new fenders were added.


They fit perfect. Took a 5000 mile trip this summer and was glad I had the option of applying grease to the bearings.

Still working a year later however a side note. Do not over grease as it will leak onto the inside of the drum and prevent the brakes from grabbing.
Virgel - 07/10/2022


I installed these on out travel trailer and they fit perfectly. It took less than an hour to install.


great product and price


Usually great products and service, but this experience was not so. If you don't have inventory then don't allow the order to go through without some warning. I wasted several days due to slow communication letting me know inventory was not readily available.


great value for the money


I purchased a kit from another online store and tried to get their solution to fit. No luck. The kit I purchased from another online store had the same advertised size as the bearing buddy that I purchased. I confirmed the size needed by measuring the inside of the hub and ordered the correct size bearing buddy from e-trailer. They were delivered today and it took just a few minutes to install. I would shop here again and buy bearing buddy again (hopefully I won’t need to)


I am pleasantly surprised with the quality of these assemblies, not having seen them in person. They are as described - substantial and of great quality...


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 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 and thanks Lisa. You have a new customer for life.


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.


Still going strong.


I put 4 of these on my 26' fifth wheel. The installation was very easy and exactly as described. I tapped them gently with a hammer to get them started and then used a block of wood and hammer to seat them fully for a nice tight fit.


The product and the service was exceptional. The Buddy Bearings fit exactly and were easy to install. The items arrived in a few days through the US mal without any problems. It was really nice to be able to track my order so I'd know when it was arriving. I will be ordering any additional items needed from because they actually had the best price I could find.


These work great. Only issue is two of rubber covers have fallen off and lost!

Sorry to hear that! We do offer replacement covers as part # BB23B
Replacement Bearing Buddy Bras - Model 23B - (Pair)
. 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.

they came in the mail when you said they would. they were exactly what i wanted, and they fit perfectly. you people know what you are doing. if i need anything else that etrailer sells, i will surely order it from you

sampson city,fl

the protectors are fine, but the rubber covers have disappeared. i pushed all the air from them when i put them on. do you sell them seperately? other than that i am happy with them. thanks wayne

Putting off greasing wheel bearings is so easy to do. Bearing Buddies make greasing wheel bearings easy because they give incentive. Only takes 5 minutes vs a couple of hours. Being on the side of the road with a break down from bad bearings isn't fun and totally preventable.


I've been using Bearing Buddies on my boat trailers since the early 80's and never had a trailer bearing fail. These are still the best solution to protect any bearings that get submerged. Make sure they are pumped up before each submergence and everything will last forever.


I bought these to upgrade my boat trailer. Perfect fit, easy install and good price. Can't ask for anything more than that.


Product arrive on time and in good cond. Fit and finish great recommend that anyone ordering these make sure u use a digital caliper as fit is critical . I wasn't able to find these local not even Napa carried this size so I did a search and found and they gave all the sizes so finding a match was easy.. Great product and great service.. Thanks Dave.

  • Bearing Buddies for 2.430 to 2.444 Inch Hub Bore
    We do have the Bearing Buddy Bearing Protectors # BB2441 or the Stainless Steel version # BB2441SS for corrosion resistance that are designed to fit hub bore diameters of 2.441 inches. This certainly falls within the range you provided but you might want to try and take one more measurement on your car hauler's hub bore just to be sure it matches. I have attached a short video review that you can check out as well.

  • 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.

  • How to Remove Bearing Buddy Trailer Bearing Protectors
    Bearing Buddies like # BB2441 fit very tight into a trailer hub. In order to get them out, you will need to use a rubber mallet and persuade them out. Once the Bearing Buddy starts to unseat from the hub you can grab it and wiggle it out.

  • 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.

  • 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.

  • 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.

  • 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 not...

  • How Do I Determine What Bearing Buddy Bearing Protectors I Need for My 2006 Pilgrim Cirrus Camper
    In order to see if the Bearing Buddy Bearing Protectors, # BB2441, are the correct ones for your trailer, you will need to measure the inner diameter of your hub bore. This measurement needs to be very accurate so you will want to use a dial caliper. If the inner diameter of your hub bore is 2.441 inches, # BB2441 will work for you. If it is not, I am attaching a link to all of the Bearing Buddy Bearing Protectors that we have available. Take your measurement and match it to one of the...

    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...

  • How to Order The Correct Bearing Buddy Size For A 1998 Homemade Trailer
    If you will remove the wheel on your trailer and pull your wheel bearings and get the outer wheel bearing part number that would help you with which Bearing Buddy to use. The reason you have to go to such lengths to find out what Bearing Buddy Kit you need is that there are so many different variations in bearing/spindle/seal combinations that the only way to be sure you have the right part is to check the equipment you have. The Bearing Buddy pages also have listings on them for what...

  • 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...

  • How to Determine Correct Bearing Buddies for Trailer
    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.

  • Does Bearing Buddy Replace Bearing Packing on Trailer Hub
    With Bearing Buddies it is still recommended that you pack the bearings by hand. The Bearing Buddy can only push grease through the front of the hub which can be helpful but does not take the place of packing the bearings properly by hand. I honestly am not the biggest fan of the Bearing Buddies only because it is too easy for people to over fill their hubs with grease which eventually blows out the seal like you mentioned.

  • Bearing Buddy that Fits Trailer Hub Dust Cap Bore of 2.374 inch

  • How To Check If the Seal On the Bearing Buddy Bearing Protectors Is Working Correctly
    If there is any grease outside the hub or if there is water inside the hub then that would indicate that the seal on the Bearing Buddy Bearing Protectors like part # BB2441 is compromised and would need to be replaced. That said, I have not heard of many instances where the seal failed so this is really not an issue to worry about. There is a relief valve built-in so overfilling won't damage the seal on the Bearing Buddy.

  • Does EZ Lube Spindle Eliminate Need to Remove Hub Bearings and Clean/Repack Them
    This is a common misconception but nothing replaces taking the hubs completely apart, cleaning them, and then repacking them with fresh grease. The EZ lube setups sound great in theory but they more often than not end up allowing people to overfill the hub with grease which then blows out the seal. I attached a video on cleaning and replacing hubs and bearings for you to check out as well.

    The bearing buddies are definitely the way to go to keep your bearings properly greased and protected during submersion. The Bearing Buddy Bearing Protectors part # BB2441 are for hub bores that are 2.441". That is the bore found commonly of 5,200 lb. axles but always good to take a quick measure to ensure they will work. I have linked a video I did on them if you would like to check it out. You should also remember to remove the grease zerk to ensure the bearing buddy seats properly.

  • How to Grease Hubs With a Bearing Buddy Installed.
    When repacking your bearings, you do not want to have the whole hub filled with grease. You basically just want to get the inner and outer bearings and their races greased up and moving smoothly.

When it is full, grease will seep around the edges of the piston and into the barrel. This...

Seals are typically designed to last the lifetime of your trailer but may need to be replaced for a number of reasons. If the seal is no longer round or the rubber seems to be dry rotted, the seal will have to be replaced. Removing the grease...

  • Do Trailer Wheel Bearings Need Repacking if Bearing Buddy Bearing Protectors Are Used
