Got the whole bed bounce at around 52 to 55. But it also bounces alot while braking, and it's really damn annoying. I've traded suspension from sides tires psi is good. Now what would cause this? 06 v6.

 

mine use to have it really bad but i just blamed it on my tires, they were wearing very bad so here recently i got them rotated and my truck aligned and now i've noticed that the bed bounce went away. just something to think about.

 

if your lifted with M/T's you can blame it on that. rotate them.

 

No lift, well a 2.5 lvl, but it was there b4 I had it installed. Stock tires. And it's just the LEFT side of the bed that does it. Heard it's the cab that bounces but since it's on rubber mounts it looks like the bed.

 

mine was on the left side too. i could look in my rear view and it would look like the left corner of my bed was going about 1.5 or 2 inches up in the air. i would try getting your tires rotated if you haven't recently
