Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather tools and parts needed for inspection or replacement.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear, bulges, or foreign objects embedded in the tread.
- Use a tire pressure gauge to ensure tires are inflated to the recommended PSI.
Replace Tires (if necessary):
- Use a jack to lift the vehicle and remove the lug nuts with a socket wrench.
- Replace damaged tires with new ones and torque to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Suspension Inspection and Repair

Inspect Suspension Components:
- Visually check struts, shocks, and bushings for wear or leaks.
- Use a pry bar to test for play in suspension joints.
Replace Worn Components:
- Remove any damaged components using a socket set.
- Install new struts or shocks, ensuring proper alignment and torque specifications are followed.

4. Drivetrain Inspection

Check Drivetrain Components:
- Inspect the electric motor and transmission for any signs of wear or abnormal noise.
- Check for loose bolts or connections.
Repair or Replace Components:
- Tighten or replace any loose hardware.
- If a component is found defective, follow the manufacturer’s service manual for replacement procedures.
