Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the suspension.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands.
Remove the wheel to access suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts
- Remove the old shock absorber by unbolting it from the mounts (typically requires a socket set).
- Inspect the mounting points for rust or damage.
- Install the new shock absorber, ensuring it is properly aligned and bolted to the mounts (use manufacturer torque specifications).
Sway Bar Links and Bushings
- Remove the sway bar link by unbolting it from the sway bar and lower control arm.
- Replace with new sway bar links and bushings, ensuring a snug fit.
Control Arm Bushings
- If bushings are worn, remove the control arm by unbolting it from the frame and the hub assembly.
- Replace the bushings and reinstall the control arm, torquing bolts to specified values.

4. Reassemble Vehicle

Reattach the wheel and lower the vehicle carefully.
Reconnect the battery.
Ensure all tools are removed from under the vehicle.
