7. CAUTION: Under no circumstances is the pinion nut to be backed off to reduce preload. If reduced preload is required, a new collapsible spacer
and pinion nut must be installed.
Use the Flange Holder to hold the pinion flange while tightening the pinion nut.
^
Tighten the pinion nut, rotating the pinion occasionally to make sure the cone and roller bearings are seating properly. Take frequent cone and
roller bearing torque preload readings until the original recorded preload reading is obtained by rotating the pinion with a Nm (inch-pound)
torque wrench.
^
If the original recorded preload is lower than specifications, tighten to the appropriate specification for used bearings. If the preload is higher
than specification, tighten the nut to the original reading as recorded.
8. Install the driveshaft.
