Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Safety warning: Engage the parking brake and use wheel chocks.

2. Tire Inspection and Rotation

Remove the tire and wheel assembly from the vehicle.
Inspect the tire for bulges, cracks, or punctures.
Rotate tires if uneven wear is detected, moving front tires to rear and vice versa.

3. Wheel Balancing

Mount the tire on a wheel balancer.
Follow the balancer's procedure to determine the amount and placement of weights needed.
Attach balancing weights to the rim as indicated and recheck balance.

4. Alignment Check

Use an alignment tool to check the wheel alignment.
Adjust the camber, caster, and toe settings to manufacturer specifications.
Tighten all adjustment bolts to the specified torque.

5. Inspect and Replace Components

Check wheel bearings for smooth movement; replace if grinding or excessive play is felt.
Inspect driveshaft and CV joints for any visible wear; replace any worn components.
