Sub-steps:
1. Remove any coverings obstructing access to the electric motor mounts.
2. Inspect motor mounts for cracks or excessive wear.
3. Replace any damaged mounts with new parts (ensure to use OEM parts).

4. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear and ensure they are properly seated.
3. Check brake rotors for warping or damage; replace if necessary.

5. Suspension Component Check

Sub-steps:
1. Inspect the struts and shocks for any leaks or damage.
2. Check bushings for wear and replace if they appear cracked or hardened.
3. Ensure all suspension bolts are tightened to specifications.
