Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Worn Components

Suspension Inspection
- Remove the wheel to access the suspension components.
- Inspect struts for leaks; if leaking, replace the struts.
- Check the condition of sway bar links; replace if damaged.
Replace Struts/Shocks
- Loosen lug nuts; raise the vehicle with a jack and secure with jack stands.
- Remove the wheel.
- Unbolt the strut from the top mount (inside the engine bay) and lower control arm.
- Replace with new strut/shock; ensure it is torqued to manufacturer specifications (usually around 50-70 ft-lbs).

3. Replace Sway Bar Links

Use a socket to remove the nuts from the sway bar links.
Install new sway bar links and torque to specifications (typically around 20-30 ft-lbs).

4. Reassemble and Test

Reattach the wheel and torque lug nuts to specifications (usually around 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
Lower the vehicle and perform a test drive to ensure the noise is resolved.
