Disconnect the battery if working on electronic components.

2. Tire Inspection and Replacement

Inspect Tires
- Check all tires for uneven wear, bulges, or other damage.
- Measure tire pressure and inflate to the manufacturer's recommended levels.
Replace Tires (if necessary)
- Use a jack to lift the vehicle and remove the wheel lug nuts with a socket wrench.
- Replace damaged tires with new ones, ensuring they match the specifications (size, type) of the original tires.
- Reinstall lug nuts and torque them to the manufacturer’s specifications.

3. Suspension and Drivetrain Inspection

Inspect Suspension Components
- Visually check control arms, bushings, and struts for wear.
- Replace any worn or damaged parts.
Drivetrain Inspection
- Inspect the driveshaft and CV joints for play or damage.
- Replace any damaged components as needed.

4. Engine and Transmission Mount Inspection

Check Mounts
- Inspect engine and transmission mounts for cracks or excessive wear.
- Replace mounts if they show signs of deterioration.

5. Wheel Balancing

Balance Wheels
- Remove the wheels and take them to a tire shop for professional balancing.
- Reinstall the balanced wheels and torque to manufacturer specifications.
