Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire iron, torque wrench, OBD-II scanner, inspection mirror.
Ensure the vehicle is on a flat surface, and turn off the ignition. Disconnect the 12V battery for safety.

2. Tire Inspection

Sub-steps:
1. Loosen the lug nuts on the front and rear tires.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the tires and inspect for uneven wear, bulges, or foreign objects.
4. Replace tires if damaged or excessively worn.
5. Reinstall the tires and torque lug nuts to the manufacturer’s specification (usually 80-100 ft-lbs).

3. Drivetrain Inspection

Sub-steps:
1. Visually inspect the driveshaft and associated components for any signs of damage or looseness.
2. Check the motor mounts for wear or fatigue.
3. If any issues are found, replace the damaged components following the manufacturer's specifications.

4. Wheel Bearing Inspection

Sub-steps:
1. Spin each wheel by hand to listen for grinding noises.
2. Check for play by rocking the wheel back and forth.
3. If noise or play is detected, replace the wheel bearings, ensuring proper torque specifications during installation.

5. Suspension Component Check

Sub-steps:
1. Inspect all visible suspension components, including control arms, bushings, and struts for wear.
2. Replace any worn components, ensuring to follow torque specifications for all fasteners.
