Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where noise is coming from).
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Worn Suspension Components

Check Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Inspect for oil leaks or physical damage.
- If damaged, disconnect the strut from the mount and lower control arm, and replace with new strut/shock.
Inspect Sway Bar Links:
- Check for wear and tear on links and bushings.
- If damaged, remove the bolts securing the links and replace with new ones.
Check Bushings:
- Inspect control arm bushings for cracks or excessive wear.
- If worn, press out the old bushings and press in new ones.

4. Reassemble and Lower the Vehicle

Reattach all components in reverse order of removal.
Ensure all bolts are torqued to the manufacturer's specifications.
Reinstall the wheel and lower the vehicle back to the ground.
