Solution

1. Preparation

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

2. Inspect and Inflate Tires

Use a tire pressure gauge to check the pressure in all tires.
Inflate tires to the manufacturer's recommended pressure (usually found on the driver’s door jamb).
Inspect tread depth with a tread depth gauge; replace any tires that are significantly worn.

3. Wheel and Tire Inspection

Remove each wheel using a socket set to loosen lug nuts (follow a star pattern).
Examine each tire for damage, such as cuts, bulges, or punctures.
Check wheel rims for any signs of bending or damage.
Clean the mounting surface of the wheel hub to ensure proper fitment.

4. Wheel Alignment

Set up the vehicle on a four-wheel alignment machine.
Adjust the alignment settings to manufacturer specifications (find specifications in the service manual).
Complete necessary adjustments to camber, caster, and toe angles.

5. Tire Balancing

Mount each tire on a dynamic tire balancer.
Spin the tire and add weights as necessary to ensure it is balanced evenly.
Reinstall the balanced tires onto the vehicle, tightening lug nuts to the manufacturer’s specified torque (usually around 100 ft-lbs).
