My 93 XJS has some movement on the rear upper shock bushings on one side. If the shocks are still decent can just the bushings be replaced? It is a round eyelet type bushing,I always thought that type of bushing was a permanent part of the shock itself, it would be nice to replace it with perhaps poly? I need to reseal the differential this winter and it would be nice to take care of everything back there.

 

Item number 4; most specialists can supply them and if you are going to mess about with the diff then I would strongly suggest that you replace all the bushes: shocks, radius arms, anti-roll bar and cage mounts, it will transform the way that car handles.
