Solution

1. Preparation

Tools Required: Floor jack, jack stands, socket set, torque wrench, differential fluid, drain pan, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool before starting the repair.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket wrench and allow the fluid to drain completely.
Inspect the drained fluid for metal shavings or debris, which may indicate internal damage.

3. Inspect and Replace Differential Components

Inspect Bearings and Gears: Remove the differential cover using a socket set. Check the condition of the gears, bearings, and shims for wear or damage.
Replace Worn Components: If any gears or bearings are damaged, replace them with OEM parts. Ensure proper alignment and fitting.
Reassemble Differential: Clean the mating surfaces of the differential cover and apply a new gasket or RTV sealant. Reinstall the differential cover and torque the bolts to the manufacturer’s specifications.

4. Fill Differential with New Fluid

Reinstall the drain plug and tighten to the specified torque.
Fill the differential with new fluid through the fill hole until it reaches the correct level, as specified in the owner's manual.

5. Test Drive

Lower the vehicle and perform a test drive to ensure the noise has been resolved. Monitor for any unusual sounds or vibrations.
