Final Drive Carrier and Differential Assembly

Disassembly Note

Note: If damage is detected during the checking procedure, a new differential should be installed.





1. Inspect the differential:
1 Differential housing
2 Differential bearing shim
3 Differential housing bearing
4 Pinion shaft roll pin
5 Pinion shaft
6 Pinion thrust washer
7 Pinion gear
8 Side gear thrust washer
9 Differential side gear

Caution: Do not disassemble the planet carrier.

Note: If the measurement exceeds specification, install a new complete final drive carrier. If the measurement is within specification, continue with the diagnostic procedure.





2. Measure the final drive planet gear end play with a feeler gauge.

Note: Do not remove the final drive pinion shaft retaining ring.





3. Remove the differential pinion shaft.
1 Remove the pinion shaft roll pin.
2 Remove the differential pinion shaft.





4. Remove the pinion gears and thrust washers.
1 Turn the differential pinion gears 90 degrees and remove.





5. Remove the differential side gears and differential side gear thrust washers.
6. Clean all parts thoroughly in clean solvent and blow dry with moisture-free regulated compressed air.
7. Inspect the differential parts for damage and wear.
1 Gear teeth.
2 Thrust washer surface.
3 Thrust bearing surface.
4 Pinion shaft.





8. Inspect the final drive planet and carrier.
1 Pinion gearteeth.
2 Thrust bearing surfaces.
3 Bushing surfaces.

Assembly Note





1. Install the differential side gears and thrust washers.





2. Install the differential pinion gears and thrust washers.
1 Rotate the differential pinion gears 90 degrees.





3. Install the differential pinion shaft.
1 Push the pinion shaft in place.
2 Install the roll pin.
