Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Differential Fluid Inspection

Tools Required: Socket set, fluid pump, differential fluid.
Remove the differential fill plug using a socket.
Check the fluid level; if low, add the recommended differential fluid until it reaches the fill hole.
Inspect the fluid for metal shavings or discoloration, which may indicate internal damage.

3. Replace Differential Fluid (if necessary)

Tools Required: Drain pan, socket set, differential fluid.
Place a drain pan under the differential and remove the drain plug.
Allow the old fluid to fully drain.
Clean the drain plug and replace it with a new gasket if necessary.
Refill the differential with fresh fluid until it starts to seep from the fill hole.

4. Inspect and Replace Worn Components

Tools Required: Socket set, torque wrench, replacement parts as needed.
Check the differential housing for cracks or damage; replace if necessary.
Inspect the driveshaft for any signs of wear; replace U-joints if they are damaged.
Check CV joints for any tears or leaks; replace if necessary.

5. Reassemble and Test

Reinstall the differential fill plug and torque it to the manufacturer’s specifications.
Reconnect the battery.
Conduct a test drive to assess noise levels and ensure proper functioning.
