and if its doing this and you get on it, the u-joint is the weak link that brakes when pinion binds up against the carrier!!!! i snapped 3 u-joints in my duster the 1st weekend i got it because of pinion nut backed off! tighten'd nut up 2 times it kept getting lose, 3rd time it got the seal so i went threw it and did the bearing seal crush sleeve and new locking nut! then spot welded the sob! 9 years of no more issues with it!! had new joint in it already,probably one the reasons it was for sale so cheap!
