Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Fluid Change

Tools Required: Socket set, drain pan, new differential fluid, funnel.
Remove the drain plug using the socket set and allow the old fluid to drain completely into the pan.
Clean the drain plug and inspect for metal shavings.
Replace the drain plug with a new washer if necessary.
Fill the differential with the manufacturer-recommended fluid using a funnel until it reaches the fill hole.

3. Inspect Differential Components

Tools Required: Torque wrench, socket set, pry bar.
Remove the differential cover by loosening the bolts with the socket set.
Inspect the gears and bearings for wear, scoring, or pitting.
If any components are damaged, remove them using a pry bar and replace with new parts.
Reassemble the differential cover and torque the bolts to the manufacturer's specifications.

4. Reassemble and Test

Reconnect the battery and ensure all tools are removed from under the vehicle.
Lower the vehicle and take it for a test drive.
Monitor for any changes in noise or performance.
