- If worn, replace with OEM or high-quality aftermarket bushings.
Check Shocks/Struts:
- Inspect for signs of leaking fluid or physical damage.
- If necessary, remove the old shocks/struts by unbolting them from the mounting points.
- Install new shocks/struts, ensuring they are torqued to specifications.

3. Wheel and Tire Inspection
