Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, fluid pump, OBD-II scanner.
Ensure the vehicle is on a flat surface and securely lifted with jack stands. Disconnect the battery for safety.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential fill and drain plugs.
2. Remove the drain plug and allow old fluid to drain completely into a pan.
3. Inspect the old fluid for metal shavings or excessive debris; this can indicate internal damage.
4. Replace the drain plug with the appropriate torque specification (consult service manual for exact torque values).
5. Refill the differential with manufacturer-recommended fluid using a fluid pump until it reaches the fill plug level.

3. Inspect Rear Suspension Components

Sub-steps:
1. Visually inspect the rear control arms, bushings, and shocks for wear or damage.
2. Use a pry bar to check for any play in the bushings or joints.
3. Replace any worn or damaged components as necessary, ensuring all bolts are torqued to specifications.

4. Check Axle Shafts and Wheel Bearings

Sub-steps:
1. Remove the rear wheel and tire assembly.
2. Inspect the axle shaft for any signs of bending or damage.
3. Check the wheel bearing by trying to move the wheel in and out; any play indicates a bad bearing.
4. If the bearing is bad, follow the manufacturer's instructions to replace it.
