Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, wheel balancer, alignment machine.
Safety Warnings: Ensure vehicle is on a level surface and engage the parking brake before lifting.

2. Adjust Tire Pressure

Use a tire pressure gauge to check and adjust the tire pressure to the manufacturer’s specifications, usually found on the driver’s door jamb.

3. Tire Inspection and Replacement

Remove each wheel using a socket set, inspect for damage.
If any tires are damaged or excessively worn, replace them with new tires that meet OEM specifications.

4. Wheel Balancing

Mount the tire on a wheel balancer.
Follow the machine's instructions to add wheel weights as necessary to achieve balance.
Reinstall the balanced tire onto the vehicle and torque lug nuts to the manufacturer’s specifications (typically 76-85 lb-ft).

5. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust toe, camber, and caster settings according to the manufacturer's specifications.
Confirm that all adjustments are complete and the steering wheel is centered.

6. Suspension Component Replacement (if needed)

If any worn or damaged suspension components are found, replace them with OEM parts.
Reassemble and torque all components to the manufacturer’s specifications.
