Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if accessing electrical components.

2. Inspect and Replace Worn Components

Shock Absorbers:
- Remove the wheel and inspect the shock absorbers for leaks.
- If worn, remove the mounting bolts using a socket set and replace with new shock absorbers.
- Torque the new bolts to the manufacturer’s specifications.
Bushings:
- Check all suspension bushings for cracks or deterioration.
- If any bushings are worn, remove the control arm or component they are attached to.
- Press out the old bushings and install new ones, ensuring they are properly seated.
Sway Bar Links:
- Inspect sway bar links for play or damage.
- Remove and replace any faulty sway bar links with new ones, ensuring they are torqued to the correct specifications.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery if it was disconnected.
Test drive the vehicle to confirm that the noise has been resolved.
