Removal
1.
CAUTION: The following step must be carried out to make sure the
correct drive pinion flange retaining nut torque is achieved.
Remove the rear brake pads.
For additional information, refer to:
Brake Pads
(206-04 Rear Disc Brake,
Removal and Installation).
2. Remove the driveshaft.
For additional information, refer to:
Driveshaft
(205-01 Driveshaft,
Removal and Installation).
3. Remove the vibration damper.
4. Remove the vibration damper retaining bolt.
5. NOTE: Support the axle assembly.
Remove the axle front retaining bolts.
Remove the vibration damper bracket.
6. Remove the axle assembly rear retaining bolt.
7.
CAUTION: Make sure CV joints do not exceed 18 degrees from the
center line.
Lower the differential.
8. Install the special tool to the drive pinion flange.
9. Install a Nm (pound/inch) torque wrench on the special tool and record
the torque necessary to maintain rotation of the drive pinion gear
through several revolutions.
10. Using the special tool, install a breaker bar and remove and discard
the drive pinion flange retaining nut.
11. NOTE: Mark the pinion flange in relation to the drive pinion stem to
ensure correct alignment during installation.
Using the special tools, remove the drive pinion flange.
12. Using a suitable tool, remove and discard the drive pinion seal.
Installation
1. CAUTIONS:
Installation without the correct tool can result in early seal failure.
If the drive pinion seal becomes misaligned during installation ,
remove it and install a new one.
• NOTE: Lubricate the lips of the new drive pinion oil seal. Use a long life
grease or equivalent.
Using the special tool, install the drive pinion seal.
2.
CAUTION: Inspect the pinion flange seal journal for rust or
nicks/scratches prior to installing the pinion flange. Polish the seal journal
with a fine crocus cloth, if required.
Install the drive pinion flange.
3.
CAUTION: Do not under any circumstance, loosen the pinion nut to
reduce preload, if preload is exceeded install a new collapsible spacer and
pinion nut.
Using the special tool, hold the pinion flange while tightening the drive
pinion retaining nut.
4.
CAUTION: If the preload recorded prior to disassembly is lower
than the specification (1.7 Nm / 15 lb-in) for used bearings, tighten the
companion flange nut until the pinion preload reaches the specification
(1.7 Nm / 15 lb-in). If the preload recorded prior to disassembly is higher
than the specification for used bearings, tighten the companion flange nut
to the original reading as recorded.
• NOTE: Rotate the pinion to allow the pinion bearing to seat correctly.
Take frequent pinion bearing torque preload measurements by rotating the
pinion with a (Nm / lb-in) torque wrench.
Using the special tool, carry out a pinion bearing preload check.
5. Install the axle assembly.
6. Loosely install the axle assembly rear retaining bolt.
7. Loosely install the axle assembly front retaining bolts.
Install the vibration damper bracket.
8. Install the vibration damper bracket retaining bolt.
