- Before servicing the vehicle, refer to the precautions in the beginning
of this section.
- Remove or disconnect the following:
- Driveshaft, matchmark for reassembly
- Check the turning torque of the pinion before proceeding. It should be 2.6-4.5
inch lbs. (0.4-0.5 Nm). This is the torque that must be reached during installation
of the pinion nut.
- Pinion nut and washer using a suitable pinion flange holding tool
- Companion flange from the drive pinion
- Pry the pinion seal out of the differential carrier.
To install:
- Clean and inspect the sealing surface of the housing.
- Install or connect the following:
- New seal into the housing until the flange on the seal is flush with
the carrier. Using a seal driver.
- With the seal installed, the pinion bearing preload must be set.
- Pinion nut (a new self-locking pinion nut must be used) while holding
the flange, until the turning torque is the same as before removal. The
final pinion nut torque must be between 137-181 ft. lbs. (190-250 Nm).
- Driveshaft, align the matchmarks
- Check the level of the differential lubricant when finished.
