How To Remove and Install Grease Caps and Bearing Protectors on Trailer Hubs

Published 01/13/2010

Question:

how do you change grease caps? do they just pop out and in or do you have to disassemble any part of the hub?

Grease caps just pop out and in. The best way to get them out is to pry them with a flat head screw driver or tap them from side to side with a hammer. To install new ones, you simply gently hammer them in. Normally I use a short piece of 2x4, to help tap the grease cap or bearing protector into the end of the hub.

I have added links to a couple of videos that demonstrate removing the grease caps.
