Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use jack stands to lift and secure the rear of the vehicle for safe access.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the rear wheel to access the suspension components.

3. Inspect and Replace Worn Components

Inspect Bushings: Check the rear control arm bushings and sway bar bushings for signs of wear. If they are cracked or soft, replace them.
- Remove the bolts securing the control arm or sway bar.
- Use a bushing removal tool to extract the old bushings and install new ones.
Inspect Shock Absorbers: Check for leaks or visible damage on the rear shock absorbers.
- Remove the top and bottom mounting bolts of the shock absorber.
- Replace with new shock absorbers, ensuring to torque bolts to manufacturer specifications.

4. Lubricate Components

Apply appropriate lubricant to any moving parts, such as the sway bar links and bushings, to reduce noise.
Ensure excess lubricant is wiped away to prevent dirt accumulation.

5. Reassemble

Reattach the rear wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications.

6. Final Check

Perform a test drive to ensure the noise has been eliminated and the suspension operates smoothly.
