I tore off all the drive shafts on my 02 1500HD expecting to find one or more wore out U-Joints, but all was good. Any other areas of the truck you guys recommend i check out. Highway driving is normal as well as downshifts.

 

have the shafts balance for reassurance. not every tube is perfect, nor lasts forever. <--- so the pros have told me

 

If its just when you are slowly starting off, it could be really cupped tires.

Just thought I'd throw that in.

 

is the truck stock, lowered or lifted?

 

2" blocks with the torsion bars cranked. MODS: HP Tune, JBA Headers, Magna Flow Exhaust, Intake.

 

maybe pinon angle?
