<img src="/forums/images/graemlins/scared.gif" alt="" /> I may be way off base on this one.Have you done any rear brake work lately.I had a hell of a time adjusting my rear brakes after replacing the shoes.One side would freeze up and the whole truck would shake like crazy.I thought it was u-joints,tires,rims,anthing but the brakes.But that's what it was.I finally gottem' adjusted and the truck rides fine now.That's my nickels worth.Good Luck! <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
