Use a jack to lift the vehicle and secure it on jack stands.
Tools Required: Floor jack, jack stands.

3. Inspect and Replace Worn Components

Sway Bar Links
- Remove the sway bar link bolts using a socket set.
- Inspect the sway bar link for wear; replace if necessary.
- Install the new sway bar link and torque bolts to manufacturer specifications (typically around 40-50 Nm).
Shock Absorbers
- Remove the nuts and bolts securing the shock absorber using a socket set.
- Compare the old shock absorber with the new one; replace if worn or leaking.
- Install the new shock absorber, ensuring proper orientation, and torque the bolts to manufacturer specifications.
Strut Mounts
- If strut mounts are worn, remove the struts following the vehicle manufacturer’s instructions.
- Replace strut mounts, ensuring proper alignment during installation.
- Reassemble struts and torque all nuts/bolts to specifications.

4. Reassemble and Lower the Vehicle

Ensure all tools are removed from the work area.
Lower the vehicle gently back to the ground using the jack.
Tools Required: Floor jack.

5. Final Inspection

After reassembly, perform a visual inspection to ensure all components are properly secured.
Test drive the vehicle to ensure that the clunking sound is resolved.
