- Once the vehicle is lifted, remove the lug nuts and the wheel.
- Clean the wheel hub and the mounting surface to remove any dirt or debris.
- Place the wheel back onto the hub and hand-tighten the lug nuts in a star pattern to ensure even tightening.
- Using a torque wrench, tighten the lug nuts to the specified torque in a star pattern as well.
- Double-check the tightness of each lug nut to ensure they are all properly torqued.
- Lower the vehicle and use the torque wrench once again to verify the lug nuts’ torque.
By following these steps and adhering to the recommended torque specifications, you can ensure that your GMC Sierra’s wheels are securely fastened, minimizing the risk of accidents or damage caused by improperly tightened lug nuts.
Conclusion
Proper lug nut torque is a critical aspect of vehicle maintenance that should never be overlooked. By adhering to the manufacturer’s recommended torque specifications and following the correct procedure for torquing your GMC Sierra’s lug nuts, you can enhance safety, improve performance, and extend the lifespan of your vehicle’s wheels.
