b. Inspect Sway Bar Links and Bushings
- Locate the sway bar and its links.
- Use a wrench to remove the sway bar links if they're worn.
- Replace with new links and bushings, ensuring they are securely fastened.
c. Examine Struts and Springs
- If struts are damaged, remove the strut assembly.
- Use a spring compressor to safely detach the spring from the strut.
