I have a question about bearing buddies. My one year old trailers bearings were repacked by the dealer in the fall. Went to check them by pressing on side of piston per instructions. One side I could barely move which I assumed meant it was ok, the other side I could rock easily. I also can see the o-ring and the spring isnt as compressed as the other side. Am I low on grease there? I thought if its low on grease the piston doesnt move. The piston moves very easily. Any comments or suggestions would be great. Novice boater but loving every minute. THANKS
