- Check the condition of the shock absorbers or struts. If they are leaking or have excessive play, replace them.
- Replace any worn or damaged bushings in the control arms or sway bar links.
Exhaust System:
- Inspect the exhaust hangers and brackets for rust or damage. Replace any that are loose or broken.

4. Tighten Loose Hardware
