Why Lug Nut Torque Matters
Properly torquing the lug nuts on your 2012 Chevy Impala is crucial for the safety and performance of your vehicle.

The lug nut torque specifications for the 2012 Chevy Impala vary depending on the trim level and wheel size. It is important to note that these specifications are for factory wheels and may differ if aftermarket wheels are installed. Here are the recommended torque specifications for the different Impala models:
| Trim Level | Wheel Size | Torque (lb-ft) | Torque (Nm) |
|---|---|---|---|
| LS, LT, LTZ | 16-inch | 100 | 135 |

How to Properly Torque Lug Nuts
To ensure the lug nuts are tightened correctly, follow these steps:
- Start by using a lug wrench or a torque wrench to loosen the lug nuts on the wheel you are working on. Loosen them in a crisscross pattern to prevent warping the brake rotor.
- Once the lug nuts are loose, use a jack to lift the vehicle off the ground. Make sure to place the jack in a secure and stable location.
- Remove the lug nuts and take off the wheel.
- Clean the wheel hub and the mounting surface on the brake rotor to ensure proper contact.
- 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 recommended torque specification for your Impala model and wheel size.
- After torquing, double-check the lug nuts to ensure they are tightened correctly.
- Lower the vehicle back to the ground using the jack.
- Finally, use the torque wrench to recheck the lug nut torque after driving a short distance to confirm they have not loosened.
Importance of Regular Lug Nut Inspections
In addition to torquing the lug nuts to the correct specification, it is important to regularly inspect them for any signs of damage or wear. Over time, lug nuts can become corroded, stripped, or damaged, which can compromise their ability to securely hold the wheel in place. It is recommended to visually inspect the lug nuts whenever you have the wheels off or during routine maintenance.
- Check for any signs of rust or corrosion on the lug nuts.
- Inspect the threads of the lug nuts for any stripping or damage.
- Ensure the lug nuts are properly seated and tightened evenly.
- If any issues are found, replace the lug nuts immediately to maintain the safety of your vehicle.
Conclusion
Properly torquing the lug nuts on your 2012 Chevy Impala is essential for the safety and performance of your vehicle. By following the recommended torque specifications and regularly inspecting the lug nuts, you can ensure that your wheels are securely fastened and minimize the risk of any potential issues. Remember to always use a torque wrench and follow the proper tightening sequence to achieve the correct torque.
