Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the 12V battery to prevent any electrical issues.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers:
- Remove the wheel on the affected side using a socket set.
- Check for leaking fluid around the shocks; replace if necessary.
Replace Control Arm Bushings:
- Remove any fasteners securing the control arm.
- Use a ball joint separator to detach the control arm from the chassis.
- Replace worn bushings with new ones, ensuring proper alignment.
Tighten Loose Bolts:
- Check and tighten all bolts associated with the suspension components, including strut mounts and sway bar links.

3. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery.
Perform a test drive to confirm the noise has been resolved.
