Disconnect the battery if necessary to avoid any electrical issues during repairs.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers or hubcaps if applicable.
- Visually inspect each tire for damage or irregular wear patterns.
Replace Tires (if required):
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the lug nuts with a socket set and take off the affected tire.
- Replace with a new tire, ensuring it's the correct size and type.
- Tighten lug nuts to the manufacturer’s specified torque value (typically 80-100 ft-lbs).
- Reinstall wheel covers or hubcaps.

3. Wheel Balancing

Balance the Wheels:
- Remove the wheels from the vehicle.
- Take them to a professional tire shop for balancing.
- Ensure to balance all four wheels to maintain even performance.
- Reinstall balanced wheels on the vehicle, following the lug nut tightening procedure.

4. Suspension and Alignment Check
