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.

  • 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...

  • 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 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...

  • 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...

  • 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.

  • 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...

  • Recommended Disc Brake Kit for Trailer With Tandem 5200 lb Axles
    I suspect what you have is what's known as a 5200 lb axle. Assuming your axle uses the 25580 inner and 15123 outer bearings which are typical on axles with capacities of 5200-6000 lbs, and your existing wheels have a 6 on 5-1/2 inch bolt pattern, the Kodiak # K2HR526D disc brake kit you'd looked at would work great for you. The kit includes 2 hub/rotors, 2 brake calipers and 2 caliper mounting brackets as well as the bolts for mounting the calipers to the brackets. For a tandem axle trailer,...

  • How to Determine Correct Bearing Buddy Fit
    So in order to get the right Bearing Buddy, you'll actually need a different and more precise measurement. 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 and match the hub bore diameter to the correct Bearing Buddies. For example, the Bearing Buddy Bearing Protectors - Model 2047 # BB2047 will fit a hub bore diameter of 2.047 inches while the Bearing Buddy Bearing Protectors - Model 2441 # BB2441 fit...

  • 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. The Bearing Buddy Bearing Protectors item # BB2441 are designed to fit 2.441" hub bores, which are commonly found on 4,400...

  • Do Grease Zerks Need to be Removed to Use Bearing Buddies
    You will need to remove your grease zerks in order to use a Bearing Buddy as the two are not compatible.

  • 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...

  • 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...

  • 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.

  • 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.

  • Correct Bearing Buddy Bearing Protectors for 1996 Ranger 461 Boat Trailer

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...

  • Bearing Buddy Recommendation for the Titan Hub part # T1870000CB042
    The correct bearing buddy for the Hub part # T1870000CB042 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.

  • 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.
