Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Drain and Inspect Differential Fluid

Remove the differential drain plug using a socket set.
Allow the fluid to drain completely into a catch pan.
Inspect the fluid for metal shavings or particles. If contaminated, a full differential service is required.

3. Remove Differential Cover

Remove the bolts securing the differential cover using a socket set.
Carefully pry off the cover to avoid bending it.
Inspect the gears and bearings for signs of wear, pitting, or damage.

4. Replace Damaged Components

If any gears or bearings are damaged, replace them as necessary.
Replace any worn seals or gaskets to prevent future leaks.
Reinstall the differential cover with a new gasket or sealant, ensuring it is torqued to the manufacturer's specifications.

5. Refill Differential with Fluid

Reinstall the drain plug and torque to the manufacturer's specifications.
Fill the differential with the recommended fluid type until it reaches the fill hole level.

6. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and check for any leaks around the differential.
Test drive the vehicle to ensure the noise is resolved.
