I have this vibration like the driveshaft is outta balance when I let off just a little bit at 60 or above. If I let off the gas all the way the drag on the drive line is enough to where I don't get it. But if I let off just a little to where things are relaxed (no load) I get a vib that sounds real nasty. I just fear for my pinion bearings or my transfercase rear bearings. I've been living with it cause I really don't drive highway that much. Oh and the drive shaft yokes are timed and in line with each other. I spacered the transfer crossmember down 3/4 of an inch also. Still no help. I'm just wondering if others with the same lift (I replaced the rear springs with s-lift spring packs)have the same problem.

How much for a new rear stock driveshaft all complete (U-joints and yokes installed ready to install)??
