Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Maintenance

Check Tire Pressure
- Use a tire pressure gauge to measure each tire's pressure.
- Inflate or deflate tires to the manufacturer's recommended levels as specified in the owner’s manual.
Inspect Tires
- Visually inspect each tire for bulges, cracks, or any signs of damage.
- Measure tread depth using a tread depth gauge; replace tires if tread is below recommended levels.

3. Wheel Balancing

Remove Wheels
- Loosen lug nuts with a socket set and remove the wheels from the vehicle.
Balance Wheels
- Mount the wheels on a wheel balancing machine.
- Add weights as necessary to ensure that each wheel is balanced properly.

4. Wheel Alignment

Perform Alignment
- Use a professional alignment tool to adjust the wheel angles.
- Set the camber, caster, and toe angles to the specifications provided by the manufacturer.

5. Suspension Inspection

Visual Inspection
- Inspect control arms, bushings, and struts for any signs of wear or damage.
- Replace any worn or damaged components.
Test Suspension
- Bounce the vehicle to check for proper shock absorption and stability.
