I had noticed a while back that my rear end didn't lock like it did when it was newer so I just assumed with enough slipping over time it was getting worn, But after putting on a lift and some new tires and wheels it somehow seems to have fixed itself... kinda:rolleyes: Now its locked for the most part all the time. Kind of a pain on pavement.:eek: Anyone have any ideas where to start looking for the cause?
