Rear end lurching side to side....

[Jthoms1]

Thanks guys. I did get a four wheel alignment, double checked the torque on all of the nuts and had the tires balanced.

I did finally discover what it was! The bolt on the forward end of the rear trailing arm had fallen out. So what I was feeling was that trailing arm sliding in its spot. Just put a fresh bolt in and it handles great.

Thanks for all of the help.
