I just had all 4 of my tires road force balanced and it took some of the bounce away but i still get it right at 45mph but not as bad as it was before.
I think it has something to do with the leaf springs, I had my 4 wheeler loaded up this weekend and drove about 30 miles and didnt have any shake or bounce at all. So I at my leaf pack with the 4 wheeler in the bed and noticed that the bottom leaf that has the rubber pads on them was compressed and touching the leaf above it.. I wonder it that shorter leaf is the problem..

i would love a solution to this as well. My truck vibrates its worst at 45mph and still shakes at 60 or 75 or anything really. Enough to see the passanger side seat shake. i hate it and cannot get it fixed. i have the 20 inch fx4 rims with the pirellis. i think ill just go ahead and get the 35s with a 6 inch lift and hope that fixes it.

Its gotta be something to do with the tires...
My vibrations was at 45 and 75 mph...
my box shook...the seat... Its best described as a "pulsation".
My new "small" tires are smooth as glass..

I lowered the 2 rears to 36PSI and the 2 fronts to 39PSI and the bounce is about 95% gone.. I'll have to mess around a little more with the pressure but it mad a HUGE difference! Thanks!
BTW- No clue why the tire place put the driver's front to 60PSI.. It was ROCK hard before I let some of the air out!

You are absolutely correct! I checked my air pressure and 2 rears were @ 40PSI , Driver's front was at 60PSI and passenger's front was 45PSI.

I picked up the truck. They installed the 3rd u-joint which didn't make a difference. Then they repositioned the driveshaft 180 degrees and rotated and balanced the tires. The vibration is less but it's still there.
As written on my RO- Final road test had minor vibrations but unable to pinpoint exact source. If condition becomes more pronounced customer should return for re-evaluation under the terms of the warranty.
