Ok, I’ve searched the forums and couldn’t find my exact problem (or problems as it might be). Please help me understand if the two issues below are related or not. The Clunk When I go from Park to Reverse, I get a loud clunk. From Reverse to Drive it’s a bit smoother. No clunks, clicks or any weird sounds when I'm driving, only happens when I move through the gears (auto tranny). I suspected U-joints after reading some other posts. So a while back, while I had it in the repair shop for something else, I had them check out the U-joints while they had it up on the rack. They said the U-joints were fine and that it was normal for there to be some slack in the rear end. I am getting uneasy about driving it around not knowing what the exact problem and solution is, not to mention it just bothers the heck out of me. Where would you suggest I start looking for the problem? The Slide Starting from a stop light/sign, I can feel the entire truck kind of slide back a bit until it, for lack of a better term, “catches” or comes to rest on something. I try to accelerate slowly so I don't blow something up. I’m thinking something in the driveline? Thanks!
