Bill, let us know if it fixes your vibration. I have one in my "decoy" which I think is my right rear Crager wheel. Just haven't had time to put dial indicator on it. JoeWell, I just got the center section back for the Dart from my shop guy. The pinion and carrier bearings were shot. It didn't get anything else. Caught it in time. replaced the crush sleeve with one of them eliminator ones. Put the rearend back in yesterday. Today I pulled the Duster in the garage and going to pull the center section out of it and have the bearings replaced on that one and a new eliminator crush sleeve. That may be where the slight vibration I have had is located.
