7. Attach the socket to the torque wrench and place it on the lug nut. Apply steady pressure until the wrench clicks, indicating that the correct torque has been reached.
8. Repeat this process for all the lug nuts on each wheel.
9. Once all the lug nuts have been properly torqued, lower the vehicle back to the ground using the jack.
10. Finally, double-check all the lug nuts to ensure they are tightened to the correct torque specification.
Conclusion
Properly torquing the lug nuts on your 2002 GMC Sierra 1500 is crucial for the safety and performance of your vehicle.
