2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on where the noise is originating.
Secure it with jack stands for safety.

3. Inspect and Replace Components

A. Suspension Inspection

Tools Required: Socket set, torque wrench
Inspect struts and shocks for leaks or physical damage.
Check sway bar links and bushings for wear.
If any component is damaged or worn, proceed to replace it.

B. Replace Worn Struts/Shocks

Remove the Wheel:
- Use a lug wrench to remove the wheel.
Unbolt the Strut/Shock:
- Remove the upper and lower mounting bolts using the socket set.
Install New Strut/Shock:
- Position the new strut/shock in place and secure it with the bolts. Torque to manufacturer specifications (usually around 40-50 lb-ft).

C. Replace Sway Bar Links/Bushings (if necessary)

Remove Sway Bar Links:
- Unbolt the sway bar link from the sway bar and lower control arm.
Install New Links/Bushings:
- Attach the new sway bar link and torque to specifications.
