Tire bouncing severely
I have a 2007 F-250 FX4 6" lift 37" TOYO'S and I have just started to experience my tire violently bouncing after hitting bumps in the road at a moderate speed (60mph +/-) The tires have been balanced and rotated but it doesn't help. Sometimes the truck bounces so bad I have to hit the brakes just to control the truck.
Any one have any clues on what may cause this? Almost scared to drive it now.

First off, welcome to the site! You can find a lot of good info here. Are you sure it's a bounce and not the dreaded "death wobble"? The general consensus is that once you go larger on your tires, the stock steering damper is pretty inadequate. If you do a search on "death wobble", you will find a lot of threads on that subject.

It surely felt like "death wobble" the first time it happened, I thought I was going to die. I had the truck lifted by a reputable 4 wheel parts house here in Texas. Thanks for the info now I know where to start to try to correct the problem.
What shocks would you recommend? I have Ranchos now and not to impressed.
Does it help to put double shocks all the way around?

Is the steering wheel oscillating back and forth or is the tire bouncing up & down? For the steering wheel oscillation a dual shock steering stabalizer will help. For tires not staying on the ground alot of people will recommend Bilstein shocks.

Did the bouncing start immediately after the lift & tires? You might have a broken belt inside the tire that could cause a bounce at highway speeds.

I had the same thing with mine with only a 3" lift and it was the death wobble. I was right sideways a couple of times and nearly $h1t myself both times.
Get yourself a dual shock steering stabilizer and have a alignment shop adjust the camber angle. I think mine are 0.5 shims which ended in a net result of 0.76 and 1.2 degrees camber. The numbers are off set to allow for road crown from the factory. No more wobble and I can hit the wash boards full on now without loosing control.
I would also suggest a new set of good quality shocks. I guessing that you got Ranchos on yours? Go with Kore, Bilisteen or other good quality shock on all four corners. If you plan to keep the truck maybe go with dual shock towers in the front as that is a lot of extra weight to stop from bottoming out.

I had the lift installed the day after I purchased the truck 09/06/06. I have 36K on it and it just recently started the "death wobble". I took it in today had all of the weights stripped from the wheel and started from scratch. On the way home a could feel it start and it got worse. I guess the next step would be new shocks?
I have no clue. The is the first time I have ever experienced this in a "lifted" truck.
Would tire pressure have anything to do with it?

Tire Pressure could have some to do with it, but I would strongly recommend an upgraded steering stabilizer with those 37's and, as Kusto recommended, get the camber angle corrected by a good alignment shop.

why does everybody think steering stabs are the cure all for all this stuff?
I have been running my 37's without steering stabs for almost a year now - trying to find another noise but have no issues keeping the truck on the road and such

I had a 4 wheel parts house put on a Pro Comp dual stabilzer but they told me they could not align it due to the fact that my upper and lower ball joints on both sides were worn badly, now this truck has 39k miles on it and I thought it was strange the ball joints be worn that bad. I took it in to a Ford dealership to get a second opinion. They told me to keep my $1100.00 because the ball joints were fine.
Now here is my question they told me running a lifted truck with big tires I should put 60psi in each tire but the tires are only rated for 50 psi max. Anyone out there know if this is true / safe?
By the way the dual stabilizer stopped the "DEATH WOBBLE"
Thanks for everyones input
