Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety warning: Use wheel chocks to prevent the vehicle from rolling.

2. Tire Balancing

Tools Required: Tire balancer, jack, jack stands
Instructions:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels from the vehicle.
3. Mount each wheel onto the tire balancer and spin to check for balance.
