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.

This product is just great. I've used these on my other trailers and I swear by them. They stay in place under very rough conditions and do a fine job of keeping the bearings greased.



by:

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.

Great product, Good company and super fast shipping

Perfectly! Can’t go wrong with bearing buddy



by:

Haven't put it on yet,but the service and the tome it took to get it was excellent. Went to the dealer to get a buddy bearing they were all you need the Vin number of your trailer and what kind of axle it has,went Google Drive it and 3 minutes later had it ordered 6 days later I had it.



by:

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.



by:

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.



by:

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.

I work as a fisheries biologist for a state agency and travel hundreds of miles every week with my boat. These bearing buddies and other bearing products have worked great and were a huge upgrade over other trailer hub products I've had in the past. So far no issues.



by:

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 etrailer.com because they actually had the best price I could find.



by:

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.



by:

Work great, have absolutely no problems with these bearing caps. Work much better than the etrailer brand caps I ordered at the exact same time for my other trailer.



by:

Worked out great and quickly delivered.



by:

Purchased for my Utility trailer, fast shipping , perfect fit , great selection , have purchased fenders etc from etrailer before very happy with all my purchases



by:

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.



by:

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

Thanks for the follow up and reply. We do indeed have the replacement covers that you are looking for, and those are part # BB23B.

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.



by:

Nice item and very easy to install, trouble free traveling.



by:

These are the BEST hands down! The originals, a must have if you want to keep your axles in optimum dependability. Easy to install, easy to service, and peace of mine knowing the bearings are greased. Great customer service and knowlageable help with getting the correct size.



by:

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.

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.



by:

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!



by:

Great customer service and shipped fast.

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.

  • Is There A Bearing Buddy That Will Replace A Tie Down Engineering 48399GA Turbo Lube Cap?
    From what I could find, the Tie Down Engineering 48399GA Turbo Lube cap you have will measure 2.33" at the threads. This is a pretty odd size and, unfortunately, there is not a Bearing Buddy kit currently available to fit this. The closest we have to this size will be the Bearing Buddy # BB2441T-SS (2.441" hub bore) or Bearing Buddy # BB2328 (2.328" hub bore), which is not threaded. The only way we can get a Bearing Buddy for you would be to replace the hubs with something that has a more...

  • 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 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 can't...

  • Which Bearing Buddy is a Fit for 5,200 lb Trailer Axle

  • Bearing Buddy Fitment
    Thanks for reaching out Will. There are a couple of ways we can determine the correct Bearing Buddy for your trailer. The first, which it sounds like you've already done, is to measure the inside diameter of the hub bore. You can also measure the outside diameter of the existing grease cap for comparison. If your hub bore does measure exactly 2.500 inches, unfortunately, we don't carry a Bearing Buddy that will fit that size. The closest smaller option is the Bearing Buddy Bearing Protectors...

  • 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...

  • Correct Electric Brakes for Dexter SLR P-16 6,000 Lb Trailer Axle
    I spoke with Dexter and they were able to confirm this is a 6,000 lb axle so for a compatible brake assembly I recommend the Dexter Electric Trailer Brake Kit part # 23-105-106 which works with the Dexter Trailer Hub and Drum Assembly part # 8-201-9UC3-EZ. If you don't already have the wiring in place then you'll also need the Epicord 7-Way Molded Trailer Plug with Junction Box part # 277-000141.

  • Do Bearings Need to be Repacked With Bearing Buddy
    There is no need to further re-pack the bearings with the Bearing Buddies like the Bearing Buddy Bearing Protectors - Model 2441 - Chrome Plated (Pair) # BB2441. So long as you maintain the grease levels, repacking the bearings isn't necessary, like you mentioned. You'll just add grease, and they have an automatic pressure-relief feature to prevent overfilling, as grease will seep around the edges when they are full. In regard to the correct fit of Bearing Buddies on your trailer, while...

  • Do Trailer Wheel Bearings Need Repacking if Bearing Buddy Bearing Protectors Are Used
    Technically speaking, once the bearings are initially packed, you shouldn't need to repack them. I'd still recommend breaking the hub down occasionally to inspect the bearings and races to make sure everything's in good condition.

  • How to Find the Correct Bearing Buddy for a Ranger Trailer
    That is a great question and in order for both of us to find the answer you're going to need to use a digital caliper like item # PTW80157 to take an accurate measurement of your Ranger trailer's hub's bore. There's no database I can look at that will tell me what's on a trailer made recently let alone one from 1989 so I am sorry I can't just give you a part number.

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.

  • Correct Bearing Buddy Bearing Protectors for 1996 Ranger 461 Boat Trailer
    In order to determine which Bearing Buddy Bearing Protectors you need you will need to measure the diameter of the hub bore on your trailer. I recommend using a digital caliper like the # PTW2993 in order to get an accurate measurement. Once you have this measurement you will be able to select the correct Bearing Buddy. For example, if you found that you had a 2.441" hub bore you could use the # BB2441. I have attached a picture showing where you need to measure, along with a link to all...

  • How Often Do Seals Need to be Replaced on Bearings with Bearing Buddies
    The Bearing Buddy Bearing Protectors # BB2441 provide premium protection for your wheel bearings. It is still recommended that you inspect the bearings, races, and seals every 12 months or 12,000 miles to ensure reliable performance on your trailer. 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...

    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 2.437...

    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.

    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.

    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 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. I attached a video of the process that should help you out as well. If you are using a Bearing Buddy, like the # BB2441, there is actually an automatic pressure-relief feature built into the Bearing Buddy. When it is full, grease will seep around the edges of the piston and into the barrel. This...

  • 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.

  • Should Bearing Buddy Actually Move When Adding Grease to Know when to Stop
    It's actually very easy to over fill trailer hubs with grease with Bearing Buddies so I would not recommend continuing to add grease with yours as you'll most likely blow out the seal and cause bigger problems. If you've added a couple shots already I would either leave it as-is or pull the hub and repack it by hand.

    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.
