ChrisAdams; you are correct and I know I need to get into the dealer. I just don't have much luck with them. I know I was being contradictory in my disciption but it is such an unusual feeling that it is hard to explain. I was recently in a Hydroplane accident where I went off the road and rolled my '99 Ford Ranger XLT. So I am probably a little paranoid. But the best I can describe what is happening is when the front tires hit the bump it jerks the steering wheel hard at first then briefly feels like the truck lifts up (Like a hydroplane) then when the back tires hit the rear end (or bed??) jumps to the right. I think this is when I really get nervous, feels like I am going to roll again.

I'll get to the dealer sometime this week, let you know.
