| 17-inch | 140-150 | 190-203 |
| 18-inch | 140-150 | 190-203 |
| 20-inch | 140-150 | 190-203 |
Steps to Properly Torque Lug Nuts
Now that you have the torque specifications for your 2002 GMC Sierra, let’s go through the steps to properly torque the lug nuts:
- Ensure that your vehicle is parked on a level surface and the parking brake is engaged.
- Using a lug wrench or a torque wrench, loosen the lug nuts on each wheel before lifting the vehicle.
- Use a jack to lift the vehicle off the ground, ensuring that it is stable and secure.
- Remove the loosened lug nuts and take off the wheels.
- Clean the wheel studs and the mounting surface to remove any dirt or debris.
- Place the wheel back onto the wheel studs, aligning the holes with the studs.
- Hand-tighten the lug nuts until they are snug.
- Using a torque wrench, tighten the lug nuts in a star pattern, gradually increasing the torque to the specified value.
- Double-check each lug nut to ensure they are properly torqued.
- Lower the vehicle back to the ground and give each lug nut a final check to ensure they are secure.
By following these steps and using the correct torque specifications, you can ensure that your 2002 GMC Sierra’s wheels are properly secured, minimizing the risk of accidents or wheel-related issues.
