How Much Torque to Remove Lug Nuts

By Richard S. Clark | Last Updated: February 18, 2022

It is feasible to remove lug nuts using either a cordless or a corded impact wrench. It must be done with caution to avoid overtightening the lug nut and damaging it while it is in place. After that, it becomes tough to get off the wheel and frequently needs to be cut off, which is both hazardous and may cause damage to the wheel and tire in the process. This post will provide essential facts about torque and how much torque you will need to remove the lug nuts.

What is the Safest or Most Common Torque to Use?

Torque charts that are recommended for working with lug nuts are available. You can search for one online. This will give you a good idea of where to begin depending on the size of the nut that needs to be removed from the nut socket. However, although it is rare in most instances, a safe torque level will be between 80 and 100 foot-pounds of force.

It’s likely that working loose a lug nut that has not been overtightened and is easy to remove will not even necessitate applying a large amount of torque to work on it fast and efficiently. It is a great idea to start with less torque and gradually increase it. You can hold at that level until the nut begins to move adequately with less torque, at which point you can test whether it will release completely without providing additional torque to the nut. This prevents the nut from becoming ruined or from being broken without the intent to do so.

Issues You Might Encounter When Removing the Lug Nuts

Keep in mind that nuts might get rusted or fragile due to cold temperatures, and they can snap off suddenly and unexpectedly. They are also capable of breaking internally to the point that they are unable to be removed easily. They may have rusted and become locked in one position, making it dangerous to apply too much torque on them. When working with nuts, the state of the nut is not always visible, mainly if the light source is not that bright. Examine each nut individually with an LED light source – even if you have to hold the light source directly on the object – to check everything is working properly before moving on to the next one. Having a better grasp of the material you’re working with will prevent more problems than you need to when attaching a cordless power tool to the project.

The Danger of Adding Too Much Torque

Adding too much torque can put you in danger. Over-tightening the lug nuts can cause the following bolts to

  • Break off
  • Crack
  • Loosen
  • Shear

It can harm the wheel itself and other components placed near the bolt if any of these things happen to the bolt. You may experience additional problems in addition to damaging the bolt, such as destructing the wheel hub itself, which could result in the threads being stripped out, harm to the seating surface of the alloy wheels, and possibly distorting the brake rotors, which could result in the vehicle grabbing and pulsing or overheating when the brakes are applied. Over-torquing can be a costly problem, depending on the extent of the damage done to the vehicle. This is why it is essential to properly tighten and remove lug nuts to reduce the likelihood of breaking the bolts.

The Right Way on Removing the Lug Nuts

In removing the lug nuts, the best way is to have the appropriate equipment and apply the right approach. The vehicle should be in the proper position and prepare the lug nuts to be removed.

  • Place the vehicle on a level surface and lock the doors.
  • Use the parking brake to keep the car in the park.

This secures your vehicle in place and ensures that it does not roll while the lug nuts are removed from the wheels. As soon as you realize it, you’ll need to change a tire, remove the spare tire from the vehicle, and have it ready once the original tire has been removed.

  • Remove the hubcap from the wheel.
  • Take a look at the lug nuts.

It is essential to check for rust or to see if they have been frozen. Rusty lug nuts may be easier to release using WD-40, which is available at most hardware stores.

You need to jack up the tire, and you should still leave the lug nuts on the bolts when jacking up the vehicle, but make sure they are loose enough to remove them with your hand.

Once you are ready, you can jack up the vehicle and unscrew the loosened lug nuts. Remove the flat tire from the car and replace it with a fresh tire. Then, hand-tighten the lug nuts until they’re all pressing against the wheel when you’re through. Reduce the pressure in the tire until you can remove the jack. Once the nuts are in position, you can use an impact driver to tighten them back swiftly. With a torque wrench, tighten the lug nuts until they have the proper amount of torque applied.

Remove the Lug Nuts Using an Impact Wrench

Generally, an impact wrench (also known as an impact gun) is far more powerful than an impact driver. The torque output of some models can go up to 220lb-ft in some instances. Even the most obstinate of lug nuts will break free under that amount of pressure. In fact, this is true even when using some of the more compact versions of impact drivers available.

When dealing with tough lug nuts, however, it is recommended that you utilize full-size, heavy-duty impact wrenches.

It is important not to get these two power tools mixed up. The primary function of an impact driver is for drilling and driving screws, while the impact wrench is used for removing and tightening rusted nuts and bolts that are stuck in place.

As a general rule, it’s best to remove lug nuts with an impact wrench, rather than manually with a breaker bar or lug nut wrench that you should keep in your spare tire box. Then, using your impact driver, remove the nuts from their sockets. Putting in the effort upfront makes it much easier for the impact driver to do its work later down the road. Ensure the impact wrench is level before placing it over the lug nut itself to avoid shearing off a corner of the nut. Before putting the impact wrench on the lug nut, make sure it turns in the proper direction by twisting it in another way. The use of caution and double-checking can help prevent you from overtightening the lug nuts, which will result in more difficulties.

How Much Torque Should You Use on Lug Nuts?

Torque the lug nuts on your car wheels between 80 and 100 lb-ft in general, depending on the vehicle. This is just tight enough to keep them from falling off, but not so tight that an impact driver will be unable to remove them completely. It is recommended that if you are changing tires at home, tighten the lugs until the impact driver stops, and then tighten them one more time with a regular lug wrench to ensure that they are properly secured.

Depending on the make and model of your car, the torque required to tighten the lug nuts varies. This information should be readily available in the owner’s manual of your vehicle. When tightening the lug nuts, keep in mind that you are securing the tire in place. As long as the lug nuts can be removed without difficulty, you don’t need to over-tighten them. Impact drivers can loosen lug nuts before tightening with a regular torque wrench or vice versa.

Final thoughts

If car lug nuts are torqued to about 80 to 100 ft-lbs, removing them also requires around 100 ft-lbs. Also, the amount of torque needed to remove lug nuts will depend on the make and model of your car. Some can be removed when torqued at 80 ft-lbs. others require higher than this, even higher than 100 ft-lbs. The best thing you can do is check the manual or consult a professional to avoid damaging the lug nuts.
