Question:

What does the auto check feature mean?

Expert Reply:

Grease can be added to the hub through an easily accessible grease fitting located in the center of the Bearing Buddy piston. Lubricant level can be checked by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled. If the piston won't rock or move, add grease until piston moves outward about 1/8 inch. When adding grease, always use a hand grease gun. An automatic grease gun will destroy the hub's inner seal.

I have Bearing Buddies 1980A on my trailer, and caught the trailer on my gate, resulting in breakage of the blue plastic piston. Is there a replacement piston, or do I have to buy the whole bearing protector?

Unfortunately the pistons by themselves aren't available as replacement parts from the manufacturer. Your only option will be to replace the whole 1980A (part # BB1980A) assembly.
