Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery for safety.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential fluid fill plug and drain plug.
2. Remove the drain plug and allow old fluid to completely drain into a suitable container.
3. Inspect the old fluid for metal shavings or discoloration.
4. Replace with manufacturer-recommended differential fluid (check owner's manual for specifications).
5. Reinstall the drain plug and torque it to the manufacturer's specifications (usually around 30-40 ft-lbs).

3. Inspect and Replace Differential Bearings (if necessary)

Sub-steps:
1. Remove the differential housing by unbolting it from the frame.
2. Inspect the bearings for wear using a visual inspection and feel for roughness.
3. If bearings are worn, remove and replace them with new ones.
4. Reassemble the differential housing, ensuring all seals are intact and properly seated.

4. Inspect Driveshaft and Axles

Sub-steps:
1. Remove the wheels to access the driveshaft and axles.
2. Check for any visible damage or excessive play in the joints.
3. If damage is found, replace the affected driveshaft or axle.
4. Reinstall wheels and lower the vehicle back to the ground.
