Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles for protection.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Inspect Struts/Shocks:
- Check for fluid leaks and physical damage.
- If damaged, remove and replace the struts/shocks:
  1. Remove the wheel to access the suspension components.
  2. Disconnect the strut from the knuckle and any attached components.
  3. Unbolt the strut from the top mount and remove it.
  4. Install the new strut in reverse order.
Inspect Bushings:
- Check control arm bushings for cracks or excessive wear.
- If worn, replace the bushings:
  1. Remove the control arm from the vehicle.
  2. Press out the old bushings and press in new ones.
  3. Reinstall the control arm.

4. Tighten Loose Bolts

Inspect and tighten all relevant suspension bolts to the manufacturer's torque specifications to prevent any loose components that may cause noise.

5. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle off the jack stands.
Ensure all tools are removed from under the vehicle.
