Question:
I have a 7x16 enclosed trailer with 2x 3,500 lb axles. One of the bearing buddies is leaking grease and I want to replace it. I’m not sure which to replace it with because of the hun size. Any help would be appreciated. Thanks!

Expert Reply:
The dimension you are looking for when picking out a Bearing Buddy is on the hub. You need to remove the BB and then measure the diameter of the bore with with a caliper like the # PTW80157.
The part # BB1810 is the correct Bearing Buddy if you have a bore of 1.81 inches.
With Bearing Buddies it's very easy to over fill the hubs with grease which will then cause either the grease seal to blow out or the Bearing Buddy to fail so be careful not to push in as much as you can.
