Shock Absorbers/Struts:
- Remove the bolts securing the shocks/struts to the lower control arms and upper mounts using a socket set.
- Inspect for leaks and physical damage; replace if necessary.
- Install new shocks/struts and torque bolts to manufacturer specifications.
Sway Bar Links and Bushings:
- Locate the sway bar links; remove the securing bolts using a wrench.
- Inspect bushings for wear; replace if cracked or loose.
- Install new links and bushings, ensuring proper torque settings.

4. Tighten or Replace Mounting Hardware

Check all bolts and nuts associated with the suspension and drivetrain for proper tightness.
Replace any worn or damaged hardware, ensuring all components are secure.

5. Test Drive

Lower the vehicle and perform a test drive to confirm the repair has resolved the clunking noise.
