2017 GMC Sierra Lug Nut Torque Specs
What is Lug Nut Torque?
Lug nut torque refers to the amount of force applied to tighten the lug nuts on a vehicle’s wheels. It is crucial to ensure that the lug nuts are tightened to the correct specifications to maintain the safety and integrity of the wheels.
Why is Lug Nut Torque Important?
Proper lug nut torque is essential for several reasons. Firstly, it ensures that the wheels are securely attached to the vehicle, preventing them from becoming loose or detached while driving. Secondly, it helps distribute the load evenly across the wheel studs, reducing the risk of damage or failure. Lastly, it helps prevent excessive wear and tear on the wheel studs and lug nuts themselves.
2017 GMC Sierra Lug Nut Torque Specifications
To help you properly torque the lug nuts on your 2017 GMC Sierra, here are the recommended torque specifications in both lb-ft (pound-feet) and Nm (Newton-meters):
| Wheel Size | Lug Nut Torque (lb-ft) | Lug Nut Torque (Nm) |
|---|---|---|
| 17-inch | 140-150 | 190-203 |
| 18-inch | 140-150 | 190-203 |
| 20-inch | 140-150 | 190-203 |
Steps to Properly Torque Lug Nuts
To ensure you torque the lug nuts correctly, follow these steps:
- Start by parking your GMC Sierra on a flat surface and engaging the parking brake.
- Using a lug wrench or a torque wrench, loosen each lug nut on the wheel you are working on, but do not remove them completely.
- Refer to the lug nut torque specifications chart above to determine the appropriate torque range for your wheel size.
- Using a torque wrench, tighten each lug nut in a star pattern, gradually increasing the torque until you reach the specified range.
- Double-check each lug nut to ensure they are all tightened to the correct torque.
- Repeat the process for each wheel on your GMC Sierra.
Additional Tips
- Always use a torque wrench to ensure accurate torque measurement.
- Do not over-torque the lug nuts, as this can lead to damage or breakage.
- Regularly check the lug nut torque on your GMC Sierra to ensure they remain properly tightened.
- If you are unsure about the lug nut torque specifications or how to properly torque them, consult your vehicle’s owner’s manual or contact a professional mechanic.
Conclusion
Proper lug nut torque is crucial for the safety and longevity of your 2017 GMC Sierra’s wheels. By following the recommended torque specifications and using a torque wrench, you can ensure that your lug nuts are tightened correctly. Regularly checking and maintaining the lug nut torque will help prevent any potential issues and keep your wheels securely attached to your vehicle.
