Can Bearing Buddy Be Installed on Trailer Hub If Spindle Has Grease Fitting

Question:

I want to put new bearing buddies on my trailer but not sure where to measure to know which ones I need. There is something similar on there now but the grease fittings appear to stuck. I could just replace the fittings I guess, but does it make more sense to put in new bearing buddies? If so, where do I measure to make sure I get the right ones? Thanks.

You can use Bearing Buddies on a trailer with EZ lube spindles but you'll have to remove the zerk fitting so that the Bearing Buddy can fit over it.

To pick out Bearing Buddies that fit your hub you'll need to measure the diameter of your hub bore where the cap installs and pick out a Bearing Buddy that matches this.

For example, the part # BB1781 fits a hub bore that measures 1.781 inches.
