Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Make sure the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Check for cracks or excessive wear.
- If worn, remove the control arm bolts using a socket set and replace the control arm along with new bushings.
Check Struts/Shocks
- Remove the strut assembly by unbolting it from the top mount and lower control arm.
- Inspect for leakage or damage. Replace if necessary using a strut spring compressor to safely install new struts.
Examine Sway Bar Links
- Check the sway bar links for signs of wear. If they are worn, remove and replace them with new links.

4. Reassemble and Secure Components

Reinstall all components securely, ensuring all bolts are tightened to the manufacturer's specifications using a torque wrench.
Reconnect the battery and lower the vehicle back to the ground.

5. Test Drive

Conduct a test drive to ensure the noise has been eliminated and the vehicle handles properly.
