DIFFERENTIAL CARRIER (MERITOR RS17.19.21&23) DF02–32
(2) Install the drive pinion and cage assembly into the carrier. Do not
install shims under the bearing cage.
(3) Install the bearing cage-to-carrier capscrews. Washers are not
required at this time. Hand-tighten the capscrews.
(4) Fasten a yoke or flange bar to the input yoke or flange. The bar will
hold the drive pinion in position when the nut is tightened.
(5) Tighten the drive pinion nut to the correct torque value. Refer to page
DF02-30.
(6) Remove the yoke or flange bar.
(7) Attach a torque wrench on the drive pinion nut. Rotate the drive pinion
and read the value indicated on torque wrench.
(8) If the pinion bearing preload or torque is not within 5-45 lb-in (0.56-
5.08 N

m) for new pinion bearings or 10-30 lb-in (1.13-3.39 N

m) for
used pinion bearings in good condition, remove the pinion and cage
assembly from the carrier. Adjust the spacer and repeat Steps (1) to
(7).
• To increase preload: Install a thinner bearing spacer.
•
To decrease preload: Install a thicker bearing spacer.
(9) After adjusting pinion bearing preload, remove the drive pinion and
bearing cage from the carrier. Refer to page DF02-21.
(10) Install a new triple-lip seal.
! CAUTION
The seal lips must be clean. Dirt and particles may cause a leak
between the yoke and the seal.
a. Apply the same lubricant used in the axle housing to the outer
surface of the seal and the seal bore in the bearing cage.
b. Place the drive pinion and cage assembly in a press with the seal
bore toward the top.
