4.
Install new pinion seal in housing, coat seal lips with grease, then mount driveshaft yoke on pinion shaft, lightly tapping yoke until several pinion
shaft threads protrude from yoke.
5.
Coat rear of pinion washer with suitable sealer, then install washer and new pinion nut.
6.
Hold driveshaft yoke with suitable tool, then alternately tighten pinion nut and rotate pinion until endplay is reduced to zero.
7.
When endplay is reduced to zero, check pinion bearing preload using a torque wrench.
8.
Continue tightening pinion nut in small increments until 35-40 inch lbs. of bearing preload is obtained with new bearings or 20-25 inch lbs. of
bearing preload is obtained with used bearings, rotating pinion and checking preload after each adjustment.
Exceeding preload specification will
compress collapsible spacer too far, requiring replacement of spacer. If preload specification is exceeded, spacer must be replaced and
adjustment procedure must be repeated. Do not loosen pinion nut to reduce preload.
