Tighten any loose bolts to the manufacturer's torque specifications (refer to service manual for specific torque values).

4. Replace Worn Parts

If the sway bar links or bushings are damaged, remove the old components:
- Use a socket set to remove the bolts securing the sway bar links.
- Install new links or bushings, ensuring they are properly aligned and torqued to specifications.
