Because the piston is spring loaded, the piston exerts a slight (3 psi) pressure against the grease, which maintains a slight pressure between the inside of the hub and the outside environment. If you can rock or move the piston, the hub is properly filled. Bearing Buddy will last the life of your trailer.

Also, how do you know when your bearing Buddy is full? You should see the piston extend out or the blue ring past the front of the Bearing Buddy® when it's properly filled. However, as air escapes the piston (or blue ring) is going to collapse inward. This is normal. After driving several miles, check the piston (or blue ring) to see if it has moved inward.
