Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires as necessary to reach the manufacturer's recommended pressure (usually found in the driver's door jamb).

3. Tire Balancing

Remove the wheel and tire assembly from the vehicle.
Mount the tire on a tire balancing machine.
Adjust the weights as necessary to achieve balance, ensuring no heavy spots remain.
Reinstall the wheel, tightening lug nuts to the manufacturer's specified torque (typically 140 ft-lbs for GMC Sierra).

4. Suspension Inspection

Visually inspect tie rods, control arms, ball joints, and bushings for any signs of wear or damage.
Replace any worn components with OEM or high-quality aftermarket parts.
Ensure all fasteners are torqued to the manufacturer's specifications.

5. Wheel Alignment

After balancing and suspension inspection, perform a four-wheel alignment using an alignment machine.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
Recheck alignment after a test drive to ensure it remains within specified ranges.
