Solution

1. Preparation

Gather tools and ensure safety gear is worn.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Using a jack, lift the front or rear of the vehicle depending on where the noise is occurring.
Secure the vehicle with jack stands.

3. Inspect Suspension Components

Sway Bar Links:
- Remove the nuts securing the sway bar links using a socket set.
- Inspect for any damage or wear; replace if necessary.
Struts/Shock Absorbers:
- Remove the top nuts of the strut assembly using a socket set.
- Unbolt the strut from the lower control arm.
- Check for any signs of oil leakage or physical damage; replace if necessary.

4. Replace Worn Parts

If sway bar links are worn:
- Install new sway bar links by securing them with nuts and tightening to manufacturer specifications (typically around 30 ft-lbs).
If struts/shocks are worn:
- Install new struts by reversing the removal process, ensuring all bolts are tightened to the manufacturer's torque specifications (usually between 60-80 ft-lbs).

5. Reassemble and Lower the Vehicle

Reattach any components removed during inspection.
Lower the vehicle back to the ground and remove jack stands.

6. Final Check

Ensure all fasteners are tightened correctly.
Perform a test drive to verify the repair.
