Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Inspect: Remove the wheel covers (if applicable) and inspect the tires for damage or uneven wear.
Replace: If any tires are damaged or excessively worn, replace them with new tires of the same specifications.
Tools Required: Jack, jack stands, lug wrench, tire pressure gauge.

3. Wheel Balancing

Remove Wheels: Use the lug wrench to remove the wheels.
Balance: Mount the wheels on a wheel balancer, and follow the machine's instructions to add balancing weights as necessary.
Reinstall: Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 80-100 lb-ft).
Tools Required: Wheel balancer, torque wrench.

4. Wheel Alignment

Setup: Drive the vehicle onto an alignment rack.
Adjust: Follow the equipment's instructions to adjust the camber, caster, and toe angles to the manufacturer's specifications.
Confirm: After adjustments, perform a test drive to confirm the alignment is correct.
Tools Required: Alignment machine.

5. Suspension Component Replacement (if necessary)

Inspect: Check tie rods, control arms, and bushings for wear.
