Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are cool before inspection.

2. Tire Pressure Adjustment

Remove valve caps from all four tires.
Use a tire pressure gauge to check each tire’s pressure.
Inflate each tire to the recommended PSI listed on the driver’s door jamb.

3. Tire Inspection and Replacement (if needed)

Remove each wheel using a socket set.
Inspect tread depth with a tread depth gauge.
Replace any tires showing significant wear or damage with OEM or equivalent tires.

4. Wheel Balancing

Mount the wheels on a wheel balancing machine.
Adjust weights as necessary to achieve balance.
Reinstall balanced wheels onto the vehicle, torque lug nuts to manufacturer specifications (typically 100-120 ft-lbs).

5. Wheel Alignment

Set the vehicle on an alignment rack.
Adjust camber, caster, and toe settings to manufacturer specifications.
Verify alignment is within tolerances.

6. Suspension and Brake Inspection

Inspect control arms, bushings, and tie rods for wear or play.
Replace any faulty components as necessary.
Check brake rotors for warping by measuring with a micrometer; if warped, replace with OEM rotors.
