Good Pont Keisur! I didn't think of that - it might make it worse to identify. I checked last night at 4:00pm and the Master Technician was searching the lot for stock size wheels to put on it to verify it was not brand new 33x10.5x15 BFG MT's on new Wheels...they have about 20 miles on them. That pisses me off, but maybe they will prove me and Discount Tire and BFG wrong on a good tire / mount / assy.

You said that you got your driveshaft replaced. But did you have it lengthened? I ask this because on CV jonits, allowing the shaft to be longer than stock can cause them to go out of phase. I have the same prob with my T100. As soon as I lifted the rearend 2" with add-a-leaves a vibration started. I believe it to be linked to the length of the rear drive shaft.

Gee, lifting springs don't seem like such a good idea now.
Same problem. Same results. Maybe all these mods aren't such a good idea?

It seems like the vast majority of us with this vibration/hum problem have added lifting springs.
I'm going to an off road shop and a driveline shop and pick their brains. I'm thinking shim due to the change in suspension geometry on my rig.
So far I've only spent $73 on u-joints. I don't have himileage27 $$$ to throw at this problem.
I hope you figure it out
himileage27, that's gotta sting!

If you are having problems with vibration in the rear, and the only mod was to lift, than you rear differential needs to be tilted upward toward the Transmission mount by 4 degree's - 3" lift, and by 8 degree's 6" + suspension lift. I am chasing a vibration not directly to the lift, but rather in the drivetrain / tires / steering linkage etc... Point is, the lift is necessary to do what I do with the truck, and it wouldn't be worth having if I didn't do what I do with it - Offroad wheeling is to much fun.

Yeah it stings - who said anything about having the money, I just had (past tense) room on the credit card. Its going to take me 5 years to pay this thing off. Thanks for the condolences though.
