Rotate the pinion gear occasionally to make sure the pinion bearings are seating correctly. Take 
frequent pinion bearing torque preload readings by rotating the pinion gear with an Nm 
(inch/pound) torque wrench. 

CAUTION: Do not loosen the pinion nut to reduce preload under any 

circumstance. If it is necessary to reduce preload, install a new drive 
pinion collapsible spacer and pinion nut.
