Shock Absorbers
- Remove the bolts securing the shock absorber at the top and bottom using a socket set.
- Replace with new shocks, ensuring they are oriented correctly.
- Torque the bolts to the manufacturer’s specifications.
Sway Bar Links
- Remove the sway bar links using a wrench and socket.
- Inspect for wear and replace if necessary.
- Install new sway bar links and torque to specifications.

4. Reassemble and Lower Vehicle

Reinstall any components removed during the process.
Ensure all hardware is tightened to the proper torque values.
Lower the vehicle and remove jack stands.

5. Final Checks

Recheck all nuts and bolts for tightness after the vehicle has been lowered.
Test the suspension by driving over bumps to ensure the clunking noise is resolved.
