How to Properly Torque Lug Nuts
- Start by ensuring that your vehicle is parked on a flat surface and the parking brake is engaged.
- Using a lug wrench or a torque wrench, loosen the lug nuts on the wheel you intend to work on. Do not remove them completely at this stage.
- Consult your vehicle’s owner’s manual or the torque specifications chart above to determine the appropriate torque value for your lug nuts.
- Attach the appropriate socket to your torque wrench and set it to the recommended torque value.
- Tighten each lug nut in a star pattern, alternating between nuts to ensure even tightening.
- Once all the lug nuts are tightened, double-check the torque by going over each nut again in the same star pattern.
- Finally, repeat the process for each wheel on your vehicle.
Additional Tips
- Always use a calibrated torque wrench for accurate torque measurement.
- Do not use an impact wrench to tighten lug nuts, as it can easily over-torque them.
- Regularly check the torque of your lug nuts, especially after tire rotations or when reinstalling wheels.
- If you are unsure or uncomfortable performing this task yourself, it is recommended to consult a professional mechanic.
