Ok guys i'm at my wits end and need some help. My truck has a severe bouncing problem that wont go away. It is coming from the rear drivers side. From a stop accelerating slowly it feels like a giant egg and between 52-55 the trucks feels like its going to fall apart. I've had two different sets of rims and three different sets of tires the first were 35'' toyo a/ts then 37'' bfg m/ts and now 37'' procomp extreme at/s. All wheels and tires look and balance perfect on the machine and every one of the rims and tires have been on that corner one time or another and it's always the same. Even tried balancing beads but did nothing. last saturday we jacked the back up and drove it in the air and the corner was wobbling all over the place, we swapped tires side to side and it was the same. Then we removed the half inch spacers I had in and it looked alot better but drove the exact same. I've pretty much ruled out tires being the problem. I've had the cheap shocks that came with the lift, bilstien 5100 and now procomp mx6's and no change. I taking it in on monday to see if the axle is bent or if anything else is wrong in thier. Other than that can you guys think of anything to check for. Sorry for the long post. Thanks in advance.

Bent axle or the rim is not able to seat fully.

How can I figure out if the rims are seating all the way?

A buddy of mine had the same problem except his would hop the worst at 40-45 mph. His problem was a bent axle

sweet, is that fixable or do i have to buy a new axle?
