Conventional

Special Tools:

Disassembly
1. Remove the differential case.





2. Remove the 10 ring gear bolts.





3. CAUTION: Care should be taken not to damage the bolt hole threads.

Insert a punch in the bolt holes and drive the ring gear off.





4. NOTE: The speed sensor ring cannot be reused once removed.

Remove the speed sensor ring if required.





5. If required, use 2-Jaw Puller for Differential Case Bearings and the Step Plate Adapter to remove the differential bearings.





6. Remove the differential pinion shaft lock bolt.





7. Remove the differential pinion shaft.





8. Rotate and remove the differential pinion gears and the differential pinion thrust washers.





9. Remove the differential side gears and the differential side gear thrust washers.

Assembly





1. Use Thermally Stable Axle Lubricant XY-80W90-QL meeting Ford specification WSP-M2C197-A to lubricate the differential side gear thrust washers and the differential side gear journals.
- Position the differential side gear thrust washers on the differential side gears.





2. Position the differential side gears.





3. Use Thermally Stable Rear Axle Lubricant XY-80W90-QL meeting Ford specification WSP-M2C197-A to lubricate the differential pinion thrust washers, and the differential pinion gears and assemble.





4. Engage the differential pinion gears opposite the differential side gears.





5. Rotate the differential pinion gears to align with the differential pinion shaft bore.





6. Insert the differential pinion shaft.
- Align the hole in the differential pinion shaft with the hole in the differential case.





7. CAUTION: If a new pinion shaft lock bolt is unavailable, coat the threads with Threadlock and Sealer EOAZ-19554-AA or equivalent meeting Ford specifications WSK-M2G315-A5 and ESE-M4G204-A2 prior to installation.

Install a new differential pinion shaft lock bolt and tighten finger-tight.





8. Use Differential Side Bearing Replacer to install the new differential bearings on the differential case.





9. Press the new anti-lock speed sensor ring and the ring gear on the differential case.





10. Install the ring gear bolts.
- Apply Stud and Bearing Mount EOAZ-19554-B or equivalent meeting Ford specification WSK-M2G349-A1 to ring gear bolts.
11. Install the differential case.
