It just never ends does it?

Personally I have to use sticky weights because I take my car to the drag strip occasionally. You can't have any hammer on weights flying off at the track and taking yourself or someone else out..
If you're feeling it in the rear maybe giving the leaf spring bushings and such a good looking over so all your geometry back there is nice and straight. I'm in that same ballpark that maybe it wasn't just the Driveline that got hurt...
