5.
Install the drive pinion lock nut. Tighten to the specified torque
using Tool. Refer to
.
6.
Measure the drive pinion bearing preload with the front oil seal
resistance using Tool.
NOTE:
●
Drive pinion bearing preload should equal the measurement
taken during removal plus an additional 0.56 N·m (0.06 Kg-m,
5 in-lb).
●
If the drive pinion bearing preload is low, tighten the drive pinion lock nut in 6.8 N·m (0.69 Kg-m, 5ft-lb)
increments until the drive pinion preload is met.
CAUTION:
Never loosen the drive pinion nut to decrease drive pinion bearing preload. Do not exceed speci-
fied preload. If preload torque is exceeded a new collapsible spacer must be installed. If maximum
torque is reached prior to reaching the required preload, the collapsible spacer may have been
damaged. Replace the collapsible spacer.
7.
Install new side oil seals into the front final drive assembly. Refer to
FFD-12, "Removal and Installation"
.
8.
