Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use safety glasses and gloves for protection.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on the noise source.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Using a tire iron, loosen the lug nuts and remove the wheel to access the suspension components.

4. Inspect and Replace Components

A. Shock Absorbers

Sub-steps:
- Remove the bolts securing the shock absorbers to the strut tower and the lower control arm.
- Replace with new shock absorbers, ensuring the correct orientation.
- Torque bolts to manufacturer specifications (typically 40-50 lb-ft).

B. Control Arm Bushings

Sub-steps:
- Remove the control arm from the vehicle.
- Press out the old bushings and press in new ones.
- Reinstall the control arm and torque the bolts to specifications (generally 60-70 lb-ft).

C. Sway Bar Links

Sub-steps:
- Remove the bolts securing the sway bar links to the sway bar and lower control arm.
- Replace with new sway bar links and torque the bolts (around 30-40 lb-ft).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually 80-100 lb-ft).
