- Remove any covers or shields obstructing access to the bushings.
- Inspect for cracks or excessive wear; replace if necessary.
Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Check for fluid leaks or physical damage; replace if needed.
- Torque Specs: Ensure strut bolts are torqued to manufacturer specifications (typically around 50-70 lb-ft).
Heat Shields and Exhaust:
- Tighten any loose bolts or connections.
- Replace any damaged heat shields.

4. Reassembly
