Repair step
- Locate the twelve 10mm long 14mm hex head bolts holding on the backplate of the differential.
- Position an oil pan under the differential.
- Loosen the bottom 4 bolts first with the 14mm socket wrench. Slowly loosen the rest of the bolts in a random order until oil flows out and enters the drain pan.
Repair step
- Repeat the last step in reverse to re-tighten the bolts on the differential cover while following the star method of tightening bolts. Use a torque wrench to ensure proper torque specifications.
- Now the differential is fully sealed and ready for new oil.
Repair step
- Locate the differential filler plug.
- Use a #2 flathead screwdriver to lift the outer lip of the plug. Pinch the outer lip of the rubber filler plug between your fingers and pull off.
- Use a vacuum pump to pump in new differential fluid until the oil level reaches the bottom of the plug hole.
- Re-insert the rubber filler plug.
