So I still have this tremendous vibration in my 4x4 shifter and in my 5 speed shifter. The truck is very noisy and rough once I go over 40 mph, anything less you can't hear it or feel anything except a minor shake in the shifter.

The manual locking hubs are not installed , and the truck is in 2WD. Which means the front diff and axles do not come into play. I have replaced all fluids. Rebuilt the rear end, changed all bearings in truck (Rear, diff, front wheels). As well as changed all mounts. Still this bad vibration is there, even after all these hours of work. I'm frustrated, can anyone give me a hint as to what this might still be? Is it something maybe in the transmission?

I got a few responses last time and checked every suggestion but still the vibration is there and getting worse.

make sure the drive shaft is straight and balanced.Check the U joints for binding or wear. check the output shaft housing bushing and drive shaft yoke for excessive looseness.

i would check bent wheels and tire balance.
if you have two bad ones, the location can
be hard to find.

I'm with greg on this one. starts checking u-joints and rotate the drive shaft and watch for play anywhere. If it's a 2 peice drive shaft check the carrier bearing. also i'd have a look at the transmission/motor mounts.

just like every one else said, u-joints, check to make sure your lug nuts are tight, or a bent rim
