@bosswrench posted:Theres a thrust washer assembly on each end of the rear upright. A thick bronze-faced thrust washer is located by a very short dowel pin in each end of the lower carrier. If you're not extremely careful in reinstalling the upright assembly into the lower a-arm, ta thrust washer will slip off its dowel pin; worst case both washers slip off. This makes the whole assembly about 1/8" wider than it should be and misaligns the thrust washers. It can cause extreme tightness of the lower assembly. Hope I'm wrong, but...
Exactly...This is what I found when I rebuilt my uprights--dowel pins worn down to a nub, and the washers destroyed from misalignment during assembly.
