Use a tire pressure gauge to check the air pressure in all tires.
Inflate or deflate tires to match the manufacturer's recommended pressure, typically found in the driver’s door jamb.

3. Wheel Alignment

Attach the alignment machine sensors to each wheel according to the manufacturer's instructions.
Adjust the alignment settings based on the specifications for the GMC Sierra T1XX.
- Toe: Adjust to ensure the front tires are parallel.
- Camber: Adjust to ensure the top of the tires tilts slightly inward.
- Caster: Adjust for proper steering response.
Tighten all adjustment bolts to the manufacturer’s specified torque values.

4. Inspect and Replace Suspension Components (if needed)

If any suspension components (e.g., tie rods, control arms) are damaged, replace them.
Follow the disassembly and assembly procedures specific to the GMC Sierra T1XX for each component.
Safety warning: Ensure all components are properly secured and torqued to specifications.

5. Final Checks

Lower the vehicle back to the ground and perform a final check of the tire pressures.
Test drive the vehicle to ensure the steering wheel is centered and the vehicle tracks straight.
