Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Wear gloves and safety glasses.

2. Tire and Wheel Assessment

Inspect Tires: Remove the wheel covers if applicable and visually inspect all tires for bulges, cracks, or uneven wear.
Check Tire Pressure: Use a tire pressure gauge to check the pressure; inflate to the recommended PSI if low.

3. Wheel Balancing

Remove Wheels: Use a lug wrench to remove lug nuts and take off the wheels.
Balance Wheels: Place each wheel on a wheel balancer and adjust as necessary by adding wheel weights until balanced.
Reattach Wheels: Reinstall the wheels and tighten the lug nuts to the specified torque (typically 100-110 ft-lbs).

4. Wheel Alignment

Perform Alignment: Use alignment equipment to adjust the toe, camber, and caster angles to the manufacturer's specifications.
Test Drive: After alignment, perform a test drive to ensure the vehicle tracks straight.

5. Inspect Drivetrain and Suspension

Examine Components: Check the drive shafts, axles, and suspension bushings for any signs of wear or damage.
Replace Parts: If any components are worn, replace them with OEM parts.
