Use a jack to lift the front or rear of the vehicle, depending on the noise source.
Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Check for signs of leaking fluid or physical damage.
- If damaged, remove the old shocks/struts using a socket set.
- Install new shocks/struts according to manufacturer specifications, ensuring to torque bolts to the recommended values.
Check Sway Bar Links:
- Remove the sway bar link bolts using a wrench.
- Inspect for wear or damage, and replace if necessary.
- Install new sway bar links, torquing bolts to manufacturer specifications.
Inspect Control Arm Bushings:
- Check bushings for wear or cracks.
- If worn, remove the control arm by unbolting it from the chassis and replacing the bushings or the entire control arm.
- Reinstall and torque to specifications.

4. Reassemble and Lower Vehicle

Reinstall any components that were removed during inspection.
Lower the vehicle back to the ground and remove jack stands.
Tighten all bolts to the specified torque values.
