Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Pressure Check

Use a tire pressure gauge to check the pressure of all four tires.
Inflate or deflate as necessary to reach the manufacturer's recommended pressure.

3. Tire Inspection

Remove any wheel covers or hubcaps.
Inspect tires for uneven wear patterns, bulges, or damage.
Replace any damaged tires as needed.

4. Wheel Balancing

Remove the wheel and tire assembly from the hub.
Mount the wheel on a wheel balancer and spin it to determine balance.
Add or remove weights as necessary to achieve balance.
Reinstall the wheel and torque to manufacturer specifications (typically 70-80 ft-lbs).

5. Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust camber, caster, and toe angles according to manufacturer specifications if misaligned.

6. Suspension Inspection

Raise the vehicle and use jack stands for safety.
Visually inspect suspension components, looking for any cracks, wear, or play.
Replace any worn or damaged suspension parts (e.g., tie rods, control arms).
