Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Gather necessary tools and parts.
Lift the vehicle using a jack and secure with jack stands.

2. Inspect Suspension Components

Shock Absorbers/Struts:
- Remove the wheel to access the shock absorber.
- Check for oil leakage and physical damage.
- Tighten any loose mounting bolts.
Sway Bar Links and Bushings:
- Locate the sway bar and inspect the links for wear.
- Replace any worn bushings or links.

3. Replace Worn Components (if necessary)

Shock Absorbers/Struts Replacement:
- Remove the mounting bolts and disconnect the strut from the vehicle.
- Replace with new shock absorbers, ensuring proper alignment.
- Torque the mounting bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Sway Bar Link Replacement:
- Unbolt the sway bar link from the sway bar and control arm.
- Install new sway bar links and torque to specifications.

4. Reassemble and Test

Reattach the wheel and lower the vehicle.
Test drive to verify that the noise has been resolved.
