Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Use a jack to lift the rear of the vehicle and support it with jack stands.
2. Remove the rear wheels using a socket set.
3. Inspect the shock absorbers, bushings, and springs for damage; replace any worn or broken parts.
4. Torque new components to manufacturer specifications (check service manual for exact torque values).

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the brake caliper and rotor to access the wheel bearings.
2. Inspect the wheel bearings for play or roughness when spinning; replace if necessary.
3. Repack new bearings with high-temperature grease and install them correctly.
4. Reassemble the brake components, ensuring all bolts are torqued to specifications.

4. Check and Top Off Differential Fluid

Sub-steps:
1. Locate the rear differential fill plug and remove it.
2. If fluid is low, drain any old fluid and replace it with the manufacturer-specified differential fluid.
3. Reinstall the fill plug and ensure it is tight.

5. Final Assembly

Sub-steps:
1. Reinstall the rear wheels and lower the vehicle from jack stands.
2. Reconnect the battery and ensure all tools are removed from the engine bay.
