- Inspect the link for wear; if damaged, replace with new sway bar links.
- Torque the bolts to specifications (typically 25 Nm).
Strut Mounts
- Open the hood and remove the cover to access the top of the struts.
- Check for any signs of wear or damage. If necessary, remove the strut assembly and replace the strut mounts.
