Check all undercarriage components for looseness.
Use a socket set to tighten any loose bolts found during the inspection.
Specifically, focus on exhaust hangers and heat shields.

3. Examine and Replace Suspension Components

Tools Required: Spring compressors (if necessary), torque wrench.
Remove the wheel to access suspension components.
Inspect struts, shocks, and bushings for wear. Replace any components that show signs of damage or excessive wear.
Reassemble the wheel and torque lug nuts to manufacturer specifications.

4. Inspect and Replace Engine Mounts

Tools Required: Engine support bar (if necessary), socket set, torque wrench.
Check engine mounts by visually inspecting for cracks or excessive movement.
If damaged, replace the engine mounts following the manufacturer’s guidelines.
Ensure all bolts are torqued to specifications.

5. Test Drive
