Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal if necessary.

2. Tire Balancing

Tools Required: Wheel balancer, jack, jack stands, torque wrench.
Lift the vehicle and remove the front wheels.
Mount each wheel onto the wheel balancer and check for imbalance.
Add wheel weights as necessary to achieve balance.
Reinstall the wheels, ensuring to torque the lug nuts to the manufacturer specifications (typically 80-100 ft-lbs).

3. Tire Pressure Check

Tools Required: Tire pressure gauge.
Remove valve caps from all tires.
Check the tire pressure against the manufacturer's recommended levels (found in the owner's manual or door jamb).
Inflate or deflate tires as needed and replace valve caps.
