Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the pressure in each tire.
2. Inflate or deflate tires as necessary to match the manufacturer's recommended pressure (found on the driver's side door jamb).

2. Tire Rotation

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front tires and swap them with the rear tires to promote even wear.
3. Reinstall the tires and torque the lug nuts to the manufacturer's specifications (typically 100-140 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Drive the vehicle to an alignment shop equipped with a laser or digital alignment system.
2. Perform the alignment according to the specifications for the GMC Sierra T1XX.
3. Adjust caster, camber, and toe settings as needed to ensure proper alignment.

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components for any signs of wear or damage.
2. Replace any worn or damaged components (e.g., control arms, bushings, tie rods).
3. Recheck alignment after any suspension adjustments or replacements.
