Solution

1. Preparation

Gather tools: jack stands, socket set, differential fluid, a drain pan, and a torque wrench.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.

2. Fluid Change

Step 1: Remove the differential fill plug using the appropriate socket.
Step 2: Insert a fluid pump into the drain hole and remove old fluid into the drain pan.
Step 3: Inspect the removed fluid for metal shavings and debris, indicating internal damage.
Step 4: Replace with new differential fluid as per manufacturer specifications (typically 75W-90 or as recommended).

3. Inspect and Replace Components

Step 1: Remove the differential cover if necessary to inspect the gears.
Step 2: Check the gears for wear or damage and replace if necessary.
Step 3: Inspect bearings for play or noise and replace if worn.
Step 4: Reassemble the differential cover, ensuring the gasket is in good condition or replaced.

4. Reinstallation
