Just recently I have noticed an odd lurching (slipping/slamming) when I make a fairly sharp left and give it a little gas. It doesn't usually do this, it is very random. I have checked the bed bolts and they are all good, wheels are tight, shocks and strutts are good. There is no leaking from anywhere under anything that I can see. It's an 04 that is a 4x4. I am at a loss.
