"jumping" issue

[wkg96rs]

for whatever reason, when i hit a bump, no matter what size, my back end feels like it kicks out and jumps or slides a little bit opposite the direction im turning. i had it on a lift for three hours looking at the undercarriage and i see nothing obvious anywhere. at all. i took it to the only two garages around here i can trust and they cant find anything either.
any ideas would be greatly appreciated.

Start with the simple stuff. Have you checked your shocks to make sure none of them are blown?

I have the same problem. My dad owns an auto shop. Looks like it is the upper rear knuckle bushings (in my case). I am looking for a source for them because I can only find them with the knuckles for like $250 each.!

The upper rear knuckle bushing is included in the Prothane kit and might be in the Energy Suspension kit, as well.
