Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface, with the parking brake engaged.
Disconnect the battery to prevent any electrical issues during the repair.

2. Raise the Vehicle

Use a hydraulic jack to raise the vehicle and secure it with jack stands.
Remove the wheel corresponding to the area where noise is detected.

3. Inspect Suspension Components

Shocks/Struts: Check for leaks or signs of wear.
Control Arms: Inspect for cracks or deformation.
Bushings: Look for cracks or excessive wear; replace if necessary.
Mountings: Tighten or replace any loose or damaged mounting bolts.

4. Replace Worn Components

If shocks/struts are faulty:
- Remove the components by taking out mounting bolts.
- Install new shocks/struts and torque to manufacturer specifications.
If bushings or control arms are worn:
- Remove the affected components.
- Install new parts ensuring proper alignment and torque.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque lug nuts to manufacturer specifications.
Reconnect the battery.
