Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, socket set, differential fluid pump, drain pan, and torque wrench.
Raise the vehicle securely using a jack and support it with jack stands. Ensure it is on a level surface.
Wear safety glasses and gloves.

2. Drain the Differential Fluid

Place a drain pan under the differential.
Remove the differential drain plug using the appropriate socket.
Allow the old fluid to drain completely.
Inspect fluid for metal particles or debris indicating internal damage.

3. Remove the Differential Cover

Remove the bolts securing the differential cover using a socket set.
Gently pry the cover off with a flat-head screwdriver if it's stuck. Be careful not to damage the mating surfaces.

4. Inspect Internal Components

Check the ring and pinion gears for wear or damage.
Inspect bearings and shims for excessive play or scoring.
Rotate the gears manually to identify any binding or roughness.

5. Replace Damaged Components

If any components are damaged, replace them with OEM parts.
Ensure proper installation of bearings and gears. Torque specifications for ring gear bolts should be followed (typically around 70 ft-lbs, but verify with service manual).

6. Reassemble and Fill with New Differential Fluid

Clean the differential cover and mating surface thoroughly.
Apply a new gasket or sealant as per manufacturer specifications.
Reattach the differential cover and tighten bolts to the specified torque (typically around 30 ft-lbs).
Fill with new differential fluid (check owner’s manual for the correct type and quantity, typically 75W-90 gear oil).
