Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, wheel balancer (if available), alignment tools.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect and Balance Tires

Remove the wheel: Use the jack to lift the vehicle and secure it with jack stands. Remove the lug nuts and take off the wheel.
Check tire balance: Use a wheel balancer to determine if weights are needed. If weights are missing or the tire is out of balance, add appropriate weights according to the manufacturer's recommendations.
Reinstall the wheel: Place the wheel back on, hand-tighten the lug nuts, and lower the vehicle. Torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Check Tire Pressure

Measure tire pressure: Use a tire pressure gauge to check the pressure of each tire. Refer to the vehicle's door jamb for the recommended PSI.
Adjust pressure: Inflate or deflate the tires as necessary to match the recommended specifications.

4. Inspect Suspension and Steering Components

Visually inspect: Look for wear on control arms, tie rod ends, and ball joints. Check for any signs of damage or play.
Replace damaged parts: If any components are worn or damaged, replace them according to the manufacturer’s specifications.

5. Perform Wheel Alignment

Take the vehicle to an alignment shop: Use alignment tools to check and adjust the camber, caster, and toe to manufacturer's specifications.
Document the alignment settings: Ensure the alignment is within the specified range for proper handling.

6. Inspect Brake Rotors

Check for warping: Remove the wheel and inspect the brake rotor surface for uneven wear or warping.
Replace or resurface: If the rotors are warped or excessively worn, either resurface them or replace them with new rotors.
