    Rear Bushings Soon?

    So tonight I punched it from a stop to get on the highway on-ramp and every time it shifted (auto), it felt like the rear-end jumped up and to the left before settling back down. I get on it all the time, but tonight was the first time I felt this. The road has been slick all day and I was going slightly uphill, but is this behavior a pretty common symptom of bad bushings (subframe/trailing arms)? The car still feels planted through turns, no wandering of any sort. Is there a chance I just lost traction for a split sec?

    If they haven't been done, they need to be done anyway. There's a 100% chance they're either shot (too soft/worn) or on their way out after 20+ years. But yes that sounds like it could be the subframe bushings. Doing mine made it much snappier on shifts.

      Did you put in new OEM rubber or did you try poly?

        check your diff mount bushing too. if its in bad shape the whole subframe can move up and down.

          Will do. Did you notice any immediate (hopefully better) difference when you changed yours?

            mine wasnt to bad to begin with. I changed to a poly unit from IE, drfting is what I use my car for, so I knew the stock bushing would not last.

              I'd recommend Condor mounts. Solid subframe mounts are good, and the TAB's won't add any harshness (according to him the material will never squeak). However a solid diff mount will add a diff whine.
