on my 01 tjs front axle. the top PS arm from the axle to the frame. bushing on the axle has a metal sleeve that the bushing sits in. well my sleeve moves back and forth and makes a squeaking sound. i have a feeling that metal sleeve shouldn't move and replacing the bushing wouldn't help. do i have to weld the sleeve to stop it from moving? or dose the bushing do more them it looks like?
