Differential Case and Ring Gear-Conventional
Special Tools:
Disassembly
1. Remove the differential case.
2. Remove the bolts.
3. CAUTION: Take care not to damage the bolt hole threads.
Insert a punch in the bolt holes and drive off the ring gear.
4. Using the special tools, remove the differential bearings if necessary.
5. Remove the differential pinion shaft lock bolt.
6. Remove the differential pinion shaft.
7. Rotate and remove the differential pinion gears and differential pinion thrust washers.
8. Remove the differential side gears and the differential side gear thrust washers.
Assembly
1. Lubricate the differential side gear thrust washers and the differential side gear journals, and assemble the washers to the gears.
- Use SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL or equivalent meeting Ford specification WSP-M2C197-A.
2. Lubricate the differential pinion thrust washers and the differential pinion gears, and assemble the washers to the gears.
- Use SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL or equivalent meeting Ford specification WSP-M2C197-A.
3. Position the differential side gears and thrust washers into the differential case.
4. Engage the differential pinion gears with the differential side gears and rotate the pinion gears to align with the differential pinion shaft bore.
5. Insert the differential pinion shaft.
- Align the hole in the differential pinion shaft with the hole in the differential case.
6. Note: If a new pinion shaft lock bolt is unavailable, coat the original bolt threads with Threadlock and Sealer EOAZ-19554-AA or equivalent meeting Ford specifications WSK-M2G351-A5 prior to installation.
Install a new differential pinion shaft lock bolt and tighten finger-tight.
7. Using the special tool, install the new differential bearings.
8. CAUTION: Make sure that the notches on the case flange and the anti-lock speed sensor ring are aligned.
Press the ring gear on the differential case.
9. Install the ring gear bolts.
- Apply Stud and Bearing Mount EOAZ-19554-BA or equivalent meeting Ford specification WSK-M2G349-A1 to the ring gear bolt threads.
10. Install the differential case.
