My passenger window seems very stiff going up Now beforeeverybody starts talking about grease or replacing the little white rider piecesit's all been done. I was looking at the small motor gear that runs against themain gear .It looked like the shaft was moving up and down depending ondirection window was going. My question should it do that or has a bearing orbushing come out. I see that there are what looks like bushings sold with a completeregulator but there is no trace in door. Does anybody know
