PINION BEARING PRELOAD ADJUSTMENT
1.
Ensure that pinion and bearings are properly installed, as outlined.
2.
Hold driveshaft companion flange with suitable tool, then alternately tighten pinion nut and rotate pinion until endplay is reduced to zero.
3.
When endplay is reduced to zero, check pinion bearing preload by rotating pinion with suitable torque wrench.
4.
Continue tightening pinion nut in small increments until specified bearing preload is obtained, 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.
