5. CAUTION: Do not under any circumstance loosen the nut to reduce preload. If it is necessary to reduce preload, install a new drive pinion
collapsible spacer and nut.
CAUTION: Remove the special tool while taking preload readings with the Nm (inch-pound) torque wrench.
Use the special tool to hold the pinion flange while tightening the nut.
^
Rotate the pinion occasionally to make sure the pinion bearings seat correctly. Take frequent pinion bearing torque preload readings by
rotating the drive pinion gear with a Nm (inch/pound) torque wrench.

If the preload recorded prior to disassembly is lower than the specification for used bearings, then tighten the nut to specification. If the
preload recorded prior to disassembly is higher than the specification for used bearings, then tighten the nut to the original reading as recorded.

Refer to the torque specification for used pinion bearings.
