Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Replace Differential Fluid

Sub-steps:
1. Lift the rear of the vehicle using a jack and secure it with jack stands.
2. Locate the differential fill plug and remove it.
3. Check the fluid level; it should be at the bottom of the fill plug hole.
4. If low, drain the old fluid using a drain pan by removing the drain plug.
5. Replace with manufacturer-recommended differential fluid (typically 75W-90).
6. Reinstall the drain plug and torque it to manufacturer specifications (usually around 30 ft-lbs).
7. Refill through the fill plug until it begins to overflow, then replace the fill plug.

3. Inspect and Replace Worn Bearings

Sub-steps:
1. Remove the differential cover by unbolting it from the housing.
2. Inspect the gears and bearings for wear or damage.
3. If bearings are worn, remove them using a bearing puller.
4. Install new bearings, ensuring they are seated properly.
5. Reassemble the differential cover with a new gasket or sealant.

4. Check Drive Shaft and Universal Joints

Sub-steps:
1. Inspect the drive shaft for any visible damage or wear.
2. Check universal joints for play or binding.
3. Replace any damaged components using a socket set and torque to specifications.
