Bouncing in rear
08 f250 with 6" lift on 37s. i have put in brand new nitto G2 all terrain tires, new rims, new bilstein shocks, new steering stabilizers, tie rods, etc, but the SOB still bounces every timei drive on any road/ highways uneven or slight bumps as if the tire looses cintact with the road a few times and then smooths out again. What can it be? any idea? thank you

well i called NITTO and they calculated the psi and told me 50 psi. i took it down to 46 so i guess take it down to 40??? i Used one formula i found on Google that said 42....so i guess 46 is too much

I purchased a set of tires shortly after I purchased my truck. I really did not notice or can I recall if it had the bounce in the rear before the new tires. But shortly after the new tire install it had a bounce in the rear b/w 40 and 45mph. So annoying! I had the tires wheel/ tire matched, road forced balanced, even driveshaft balanced. sometimes it would smooth out after a balance and rotation, sometimes not. I just dealt with it. I have even read on this site that the bounce is just part of a long bed characteristic. Recently I had a new set of different brand tires installed by the same shop where the others came from and who does all the maintenance on my vehicles. Voila, the bounce is gone, truck is as smooth as silk. So, it may be the tires.

There are a LOT of things that contribute to 'beam shake' as it used to be known. If you've got a long box truck it's going to be worse than a short box truck. You've also lifted it, which doesn't help the issue. Deflating the tires can help but not always, and even if the tires are perfectly balanced you may not get rid of all of it.
Usually what helps is to put some weight in the bed. Just a couple bags of sand might be enough, right between the fender wells. This will help put some pressure on the springs and keep them from bounding.
If that DOESN'T help and it is truly a tire issue, you could try Centramatic wheel balancers. They go between your brake rotor and your wheel, and help take out imbalances. I have not used them myself (though I am considering it), but I have heard people have had very good luck with them.
