- Tools Required:
- J 33790 Differential Side Bearing Installer
INSTALL OR CONNECT
1. Thrust washers and side gears into the differential case.
- If the original gears and washers are being reused, install them on the same side from which they were removed.
2. Pinion gears.
- Position one pinion gear between the side gears and rotate the gears until the pinion gear is directly opposite the opening in the case.
- Place the other pinion gear between the side gears, making sure the hole in both pinion gears line up.
3. Thrust washers.
- Rotate the pinion gears toward the opening enough to permit the sliding in of the thrust washers.
4. Shaft and bolt.
5. Ring gear onto the differential case.
6. Bolts.
Important: Always install new bolts. Never reuse the old bolts.
- Tighten bolts in progressive steps to 80 Nm (59 ft. lbs.).
7. Side bearings using J 33790.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
