2. Inspect tires for uneven wear; replace if necessary.
3. Rotate tires if uneven wear is detected.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a wheel balancer.
3. Add weights as needed to achieve proper balance.
4. Reinstall the wheels and torque the lug nuts to the specified value (typically 140 ft-lbs for GMC Sierra).

3. Suspension Inspection

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it on jack stands.
2. Inspect control arms, ball joints, and bushings for wear or damage.
3. Replace any worn or damaged components as necessary.

4. Alignment Adjustment
