Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, stethoscope.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before starting work.

2. Remove the Wheel

Loosen the lug nuts using a lug wrench while the vehicle is on the ground.
Raise the vehicle using a jack and place it securely on jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Replace Components

Inspect the Shock Absorbers:
- Look for any signs of oil leakage.
- If found, remove the shock absorber by unbolting it from the top and bottom mount.
- Replace with new shocks, ensuring proper alignment and torque to manufacturer specifications.
Examine Bushings and Control Arms:
- Check the bushings for wear or cracks.
- If damaged, unbolt the control arms and replace the bushings or the entire control arm as necessary.
- Torque all bolts to manufacturer specifications.
Inspect the Springs:
- Examine the coil springs for any cracks or breaks.
- If damaged, remove the spring using a spring compressor and replace with new springs, ensuring they are seated correctly.

4. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specifications.

5. Final Check

Test drive the vehicle to ensure the noise has been resolved and check for proper handling.
