Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check all tire pressures.
Inflate or deflate tires to the manufacturer's recommended pressure (usually found on the driver's door jamb).
Recheck tire pressure after adjustments.

3. Tire Inspection and Replacement

Remove each wheel using a socket set.
Inspect tires for bulges, cracks, or uneven wear patterns.
If tires are worn or damaged, replace them with new tires of the same specifications.

4. Wheel Balancing

Mount the wheel on a wheel balancer.
Identify and adjust any imbalance by adding wheel weights as necessary.
Reinstall the balanced wheel to the vehicle.

5. Suspension and Alignment Check

Inspect shocks, struts, and other suspension components for wear or damage.
If any components are worn, replace them with OEM parts.
Perform a wheel alignment using an alignment machine, adjusting the camber, caster, and toe to manufacturer specifications.

6. Final Assembly

Reinstall all wheels and torque the lug nuts to the manufacturer's specifications (typically 100-110 ft-lbs).
Reconnect the negative battery terminal.
