Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Fluid pump
- Differential fluid
- Drain pan
Ensure the vehicle is on a level surface and securely lifted with jack stands.

2. Drain Old Differential Fluid

Position a drain pan under the rear differential.
Remove the drain plug using a socket wrench and allow the old fluid to completely drain into the pan.
Inspect the old fluid for metal shavings or excessive debris, indicating internal wear.

3. Inspect and Replace Differential Components

Remove the cover of the rear differential if applicable.
Inspect the ring and pinion gears for wear or damage.
Check the differential bearings for play or roughness. If worn, they should be replaced.
If any components are damaged, replace them with OEM or quality aftermarket parts.

4. Clean and Reassemble

Clean the differential cover and mating surfaces thoroughly.
Apply a new gasket or sealant as required and reinstall the cover.
Tighten the cover bolts to the manufacturer’s specified torque.

5. Fill with New Differential Fluid

Using a fluid pump, fill the differential with the appropriate type and quantity of gear oil as specified in the vehicle’s owner’s manual.
Reinstall the fill plug and torque to specifications.
