Solution

1. Preparation

Ensure the vehicle is parked on a flat surface with the engine off.
Gather tools: jack, jack stands, socket set, torque wrench, and a differential fluid pump.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Remove the differential fill plug using the socket set.
2. Use a fluid pump to extract the differential fluid and inspect it for metal shavings or debris.
3. If the fluid is dirty or low, clean the differential cover and replace the fluid with the manufacturer-recommended type (typically 75W-90 gear oil).
4. Reinstall the fill plug and torque it to the manufacturer's specifications (usually around 30-40 Nm).

3. Inspect Rear Suspension Components

Sub-steps:
1. Lift the rear of the vehicle and support it securely on jack stands.
2. Visually inspect the shock absorbers, control arms, and bushings for signs of wear or damage.
3. If any components are worn, replace them with OEM parts as necessary.

4. Check Wheel Bearings

Sub-steps:
1. Spin each rear wheel by hand and listen for noise or roughness.
2. If noise is detected, remove the wheel and inspect the wheel bearings for play or damage.
3. Replace any faulty wheel bearings with new ones, using a press if necessary.
