Solution

1. Preparation

Tools Required: Socket set, jack stands, transmission jack, torque wrench, differential fluid pump, drain pan.
Raise the vehicle using a jack and secure it with jack stands.
Allow the differential to cool if the vehicle has been driven recently.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug and allow the old fluid to completely drain out.
Inspect the old fluid for metal shavings or debris, which indicates wear.

3. Inspect Differential Components

Remove the differential cover if necessary for deeper inspection.
Check the gears and bearings for wear or damage.
Replace any damaged or worn components, using OEM parts for best results.

4. Clean and Reassemble

Clean the differential housing and cover with a suitable cleaner.
Apply a new gasket or sealant to the cover as per manufacturer specifications.
Reinstall the differential cover and tighten bolts to the specified torque settings (refer to service manual for exact torque values).

5. Refill with Differential Fluid

Use a differential fluid pump to refill the differential with new fluid, ensuring it meets the manufacturer's specifications.
Replace the fill plug and torque to the recommended specifications.
