Replacing Grease in Trailer Hub that Has Bearing Buddies

Question:

I have bearing buddies on my 3500lbs trailer for a boat. How to I replace all the grease in them? Do you just take the bearing buddy off and wipe it out?

To replace the grease in a hub that has Bearing Buddies is the same as hubs with standard grease caps. You'll want to pull the hub off, remove the seal, remove the bearings and then remove the grease the "old-fashioned way". Some people will say that you can use the Bearing Buddy to push the old grease out by just continuing to pump grease into the hub but doing this will most likely cause the seal to blow out and cause issues.

I attached a video link to this page that covers bearing repacking for you to check out as well.

For grease the LMX Red grease like part # L11390 is a really great option as it's the toughest waterproof grease on the market.
