I have an 82 4x4, with a rear drive shaft from a later 80's truck. It has a mild lift. I replaced the first U joint after about 2 years after installing the shaft. It seems like I am replacing the joint every other year now. It is the one closed to the transfer case.
I installed a new Spicer unit, and it has developed axial play in about a week. The shaft is in great shape.The shaft was blanced when installed. It seems like the clips should be thicker to take up the extra play. Any ideas?
