Solution

1. Preparation

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

2. Inspect and Replace Worn Components

A. Struts/Shocks

Remove the wheel to access the strut assembly.
Check for fluid leaks around the strut. If leaking, proceed to remove.
To remove the strut, unbolt the upper mounting bolts under the hood and lower mounting bolts at the wheel assembly.
Install new struts in reverse order, tightening to manufacturer-recommended torque specifications (typically around 30-50 ft-lbs).

B. Sway Bar Links

Locate the sway bar and its links connected to the lower control arm.
Remove the nuts attaching the sway bar links using a socket wrench.
If the links are worn or damaged, replace them with new ones, ensuring they are tightened to the specified torque (usually 30-35 ft-lbs).

C. Bushings

Inspect the control arm bushings for cracks or deterioration.
If replacement is needed, use a bushing removal tool to extract the old bushings.
Insert the new bushings and ensure they are seated properly.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Ensure all components are tightened to specifications.
Test drive the vehicle to confirm that the noise has been resolved.
