severely cut the service life of the universal joints.
During installation, damage to universal joint may occur if cross binds on needle bearings.
When tightening the bearing plates, oscillate the universal joint cross and stop tightening
capscrews at the first sign of resistance.
The front drive shaft (B) and center bearing must always be fully installed before rear drive
shaft (A) is installed.
Remove tape or wire retaining bearing plates and remove these from cross that is to be installed.
