How to Remove a Seized Lug Nut in 3 Easy Steps

Posted by Benjamin Hunting Know How

A seized lug nut can turn the simple task of changing a tire into a frustrating experience. It doesn’t have to be that way — there are a number of tricks on how to loosen a nut that just won’t budge, so you can get the job done and get back on the road. Let’s look at the basic steps you should go through when dealing with a stuck lug nut.

1. Soak It

Most of the time, a seized lug nut won’t lighten its grip due to corrosion, which happens when water, road salt and oxygen mix where the threads meet. It can also occur at the base of the nut, cementing it in place.

The least labor-intensive way to break a rusty lug nut free is by soaking it in a product like WD-40, PB Blaster or some other oil-based lubricant. Spray it at the base of the nut and wait, as long as you can, for the oil to work its way through the threads and between the nut and the metal of your hub. If you can, try leaving it overnight.

2. Choose the Right Socket

If your socket isn’t tight enough, it won’t be able to properly grip and turn the seized lug nut. In fact, a loose socket is more likely to spin around the nut and round off its edges, creating a second problem for you to deal with. Ensure that the socket you are using is the right size, and that it’s on as tight as possible before applying torque.

3. Mechanical Advantage

You can increase the amount of torque by lengthening the arm of the driver used to spin the socket. Use as long of a driver handle as you can, and then fit a piece of hollow piping over the handle to further extend the arc. This can add two to three times as much torque to that initial turning action, which is often what is needed to break the lug nut loose. You can also hammer it, or jump down on the bar (as long as it’s tightly secured), to add extra turning force.

Avoid Power Tools

While it might be tempting to use an impact wrench to remove a seized lug nut, it’s not the best idea. More often than not, an impact driver will simply round off the nut rather than break it free if it’s really stuck. The above steps — combined with patience and time — are the best options for easy lug nut removal.

Having been bitten by the car bug at a young age, I spent my formative years surrounded by Studebakers at car shows across Quebec and the northeastern United States. Over ten years of racing, restoring, and obsessing over automobiles lead me to balance science writing and automotive journalism full time.   I currently contribute as an editor to several online and print automotive publications, and I also write and consult for the pharmaceutical and medical device industry.

How do I loosen stuck lug nuts in order to change a tire?

How do I loosen car tire lug nuts (so that I can change a tire) when they are really really stuck?

I have tried turning the provided wrench, even standing and jumping on it. This worked for 4 of the lug nuts, but not the bottom-most one.

I have heard of using a rust remover/blaster, but I do not see much rust at all, and the tires are not too old if I recall correctly.

Another recommendation I see is to use a long pipe on the handle of the wrench for more torque. But even with just the wrench I seem to be warping the stock wrench with my efforts!

Some forums recommend using a 4-way lug wrench, but they do not say how to use one, or why they are better than the stock wrench. Can they provide me more torque than jumping on a standard wrench?

Finally, I am hopeful for an answer other than take it to a shop. I know I can do that, but I am trying to avoid the expense of a tow.

  • lug-nut

Remember that lug nuts are exposed to literally every element that could possibly cause corrosion. It sounds like your last nut is stuck due to some rust or oxidation that you can't see. Here's how I generally approach a badly stuck nut:

  1. Check your safety gear: eye protection, jack stands, everything to keep yourself from getting killed when this wheel finally comes loose.

  2. Get out the penetrating oil (AKA rust blaster). Really soak the bolt and nut. Now walk away and let it soak in, possibly for hours.

  3. Affix the correct socket to your breaker bar. This is a totally different beast from the stock tire iron. Its handle is much more durable and is very unlikely to bend under the torque that you're about to apply. Remember, think carefully about what's going to happen when the nut lets go. If you're pulling, it's not hard to end up punching yourself in the face. If you're pushing, don't let your fingers bash into the garage floor or other components. I've hurt myself using both methods when battling bolts (never worse than giving my wife an excuse to eyeroll me, thankfully).

  4. Try getting the nut off.

  5. Didn't work? Take a longish piece of steel pipe, stick it over the end of the breaker bar to increase the moment arm of the lever and try again.

Once I get to this point, I usually cycle between penetrating oil and a super long breaker bar. Things eventually come loose after a sufficiently long period of HULK SMASH time.

NOTE: when working with exhaust nuts and bolts, the bolt will eventually snap under enough torque. This is less likely with the much more robust wheel studs.

There are a number of things you can do to unstick the nut before turning it:

  • a lubricant or rust blaster. Keep things wet and give it time to work.

  • heat cycling. Heat it up (gently) and let it cool. Repeat. If you oil it up and point a propane torch at it, you may start a fire, so be careful. It's not so important to heat just the nut or just the stud - the cycles will do a lot of good.

  • vibrations and shocks. Rap the nut with a wrench. You don't have to hit hard; hitting over and over works. This can break the corrosion as well as help the lube work its way in.

There are several tools designed to make good use of shocks.

A handheld impact driver ($30) is a simple tool for around for just this purpose. You attach a socket, put it on the lug nut, twist, and hit with a hammer. Repeat. You could do this once a minute while the lube works its way in, and apply heat in between.

There are battery-powered impact drivers under $100 that I use for carpentry that can also do this job. If you already have a cordless drill, you can get an impact driver that uses the same battery. Loud!

Finally, you can do what the pros do - use a pneumatic impact wrench. You may be able to rent one for a single use.

Impact tools should be used with special impact-rated sockets. These use tougher steel and no chrome, so they are less likely to shatter. Eye protection is still a good idea.

Whenever I change a tire, I first break each lug nut while the car is still on the ground, with parking brake set, so everything is stable.

When a stud is in really bad shape, even after you break things lose, you may have to fight the rest of the way off the stud. It's a lot like cutting new threads. In that case, back off after every 1/4 turn or so, and keep adding lots of lube.

If you're trying to use the stock wrench, go out and buy a proper one! I've never seen a stock one that is any use, and some of them are so bad they may as well be made of chocolate...

A 4-way wrench is simply a cross-shaped bar with 4 different sizes of socket on the ends. You use the appropriate size one for your nuts, and then have effectively a t-bar, which means you can use both hands to get more leverage.

My preference, however, is for a telescopic bar wrench. These typically extend from around a foot to 2', and come with a selection of sockets for different sized nuts. Again, they simply allow you to get more leverage than the stock wrench, but are easier to store than a 4-way one, and by using the shorter length to re-tighten the nuts, avoids over-tightening (although as the comment above suggests, you should really use a torque wrench to tighten them correctly).

Another tip is to make sure your tyre supplier uses a torque wrench when they fit your tyres - many will use an air-gun which results in the nuts being done up excessivley tight (most likely the cause of your current problem).

Learn from my mistake!! I attempted to use four different chisels to 'counter rotate' the stuck nut. NEVER do this. What happens is that the chisel force drives the annular ring of the lower portion of the nut into the well where the curved face normally sits. You get the rest of the nut finaly chisseled off and you are STUCK with the measley shxxty annular ring driven and wedged into the small well. Then you have to drill and drill with, like a 5/32 drill, a whole bunch of holes and finally drive out pieces. You can drive it around the block with all nuts very loose and this shxxty annular ring is wedged way in there. Try all the other methods, heat it up, smaller socket driven on and turned, welded 2nd nut to bad nut and removing them together, whatever, BUT don't get out your chissels!!!!! You will blow nearly a day using the chisel method and have to buy a new stud and perhaps a rim as well !!!

As Bob Cross mentioned, use the breaker bar. I've had to use them to remove brake calipers in the past. In the past, I have not seen such a thing as a breaker bar readily for sale at the hardware stores where I live.

I have improvised a breaker bar using one of those metal pipes that are used for running electrical wires. Simply take your ratchet to the hardware store with you and find a suitably sized pipe that fits nicely around the ratchet handle.

All of the answers work.

But what works best for me (esp. on the side of the road!) is a 4 way tire wrench in conjunction with the screw type jack found on all cars.

Place the correct size socket on the wheel lug (nut). Position it as close to horizontal as possible. At the other end of the 4 way tire wrench, place your screw type jack and raise the height so that it supports the 4 way tire wrench in a horizontal position.

You now have a stable platform. The two free arms of the 4 way tire wrench are available for work.

Place your foot on the free arm that will turn the lug/wrench counter clockwise. With one hand on the car for balance, stand on the free arm, as close to the end as possible, with all your weight, and "kick" down if needed.

I like this method b/c you don't have to worry about stripping the edges of the lug/nut, and ruining it.

2

One. Dont jump on it. You risk stripping the lug and stud then you can't remove the tire and Have to replace the stud.

Two. Never supposed to use grease, silicon, or wd40 on tire lugs or studs. The stud remains lubricated and the lug can work itself loose when driving after having the tire changed.

You just need to not overtighten them in the first place. Some shops do this. And have a good tire iron with leverage. Apply firm gradual torque, not sudden aggressive torque like jumping on it or hitting with a hammer. These things can cause more harm than good and people that read this and follow this advice will be stranded on the side of some highway after stripping the lug or stud. my $.02

Turning the tire so that the stuck/frozen nut was at the top (12 o'clock) did it for me. Another try with a pipe extender on the tire wrench and the nut "cracked" and loosened. This is actually the easiest and should be the FIRST alternative in any of the answers above. I had already put nut loosener fluid on the stud and almost "rounded" out the corners of the lug nut with forcing the wrench, which could have made it impossible to remove except by an expensive garage repair.

Last resort... Heat the nut, and it will expand. This might help loosen it, but try this only after you have sprayed it to deaf with corrosion removing stuff. If you can see the other side, cool the lug and it will help the process. Again, last resort.

I just had this problem. I got all of them loose but one at the bottom. I tried everything it wouldnt come loose. Jacked it up took it out of gear spun the tire around so that the nut was on top. It came right off without a problem.

Heating the stud up with an acetylene torch worked great for me. Worked for days and days with breaker bars up to 8 feet long and nothing worked. Even broke 3 heavy duty 1/2" drive impact sockets. Took me a few try's to remove the nuts with the torch and then the tire iron but the heat definitely works. I wouldn't try unless it's a last resort.

A large T-bar may be the answer. I've found that if you tilt the thing at about a 45-degree angle, get a foot on the lower end and a hand on the upper, you can use your body weight to put tremendous torque on the nut without seriously misaligning the socket/nut.

I put a pipe on the handle of the standard wrench and jumped on it. I thought I was turning the nut, but I snapped the wrench (1/2 inch diam handle). Then I tried better wrenches, without success. I put the other nuts back on gently and drove about 4 miles. That did it. But if you have a flat tire its not a solution! Maybe if you drove 30 feet on the flat that would loosen the nut without harming the tire.

I had some stubborn nuts on my Range Rover. I always have trouble. Some nuts won't accept the the socket on the wrench as they have become deformed over time. I now use a ring spanner.

In frustration I tried using my jack. I place the ring spanner over the nut and used the jack to loosen the nuts enough to turn by hand. But this has failed to work on one nut. The pressures involved made me very nervous, so I backed off and have come on here for other ideas.

If you didn't take the other four off in the right order, it might help to put them back on and tighten them, then try busting the stuck one loose. Then crack them all loose in the right order. For five nuts, the right order is like you're drawing a star: go around and hit every other nut. After each one just starts to turn, then go back and loosen them more.

What can happen is if the wheel isn't heels on evenly, it can start tilting a little and this could put uneven forces on the last nut that could make it harder to remove.

In addition to going in the right order, use a 4 way tire iron and plenty of torque. See other answers.

Had a slow puncture so pumped up the tyre with my electric pump then drove to the garage to get it repaired but forgot to take my torque wrench with me. Got the fitter to use a T bar and 21mm socket to tighten the nuts then drove home to set the nuts to the recommended 80 lbs ft only to find out the first one I tried wouldn't move even with standing on a long T bar. Finally resulted in winding up my 21" long torque wrench in increments until it was at 185lbs ft and standing on it, before the nut slowly moved without the torque wrench breaking. Luckily the max setting is 220lbs ft as I was getting concerned that it was going to be back to the garage.

How to unscrew the bolts, how to unscrew the stuck bolts on the wheels. Effective ways to loosen stuck wheel bolts. How to unscrew the stuck bolts on the wheels of the car.

Wheel bolts attach the car wheel to the hub and whenever you want to change tires, get access to the suspension, brakes, you have to unscrew them. The ability to unscrew the wheel is necessary for every driver, since no one is immune from punctures. Unscrewing the bolts is not at all difficult, but if they have not been touched for a long time, they can rust. Our article will help to cope with such a problem. 9Ol000

  • with chemicals

  • Pro tips
  • Work Safety

    To prevent the vehicle from rolling away, place it on a level surface and apply the parking brake.

    Tools, fixtures, consumables

    1. Flathead screwdriver, plastic puller or wrench to remove caps.
    2. Wrench for wheel bolts.

    How to loosen bolts (step by step)

    1. Depending on the equipment, protective caps can be installed on your rims. In this case, it is necessary to dismantle the cap to gain access to the bolts. Protective caps can be fastened with bolts, metal clips or other plastic fasteners.
      In the first case, the fixing bolts of the caps can be removed only after unscrewing the wheel bolts. If you try to dismantle them before that, the caps will break.

      If caps are secured with metal latches, use a flathead screwdriver or other flat metal object as a lever to pry them off the disc. If the caps are attached with plastic nuts, you will need a plastic puller. You can use a regular wrench, but be careful not to use too much force to avoid damaging the nuts.
    2. Automobile wheels are attached to the hub with six or four bolts, which are necessary for reliable fixation of the wheel and its centering. On American cars, studs and nuts are often used, but this does not change the procedure for dismantling the wheel.
    3. Wheel wrench available as a cross or straight wrench. The cruciform product will give you the opportunity to develop more force, since it can be twisted with two hands. The bolts must be loosened while the vehicle is on the ground with all wheels. Do not jack up the machine until the bolts are loosened.
    4. Place the special wrench on the wheel bolt and turn it counterclockwise. It is important to put the wrench on the bolt head well. It is desirable to loosen the bolts along the "asterisk", as it makes it possible to maintain the centering of the wheel.

    How to loosen stuck bolts

    Check that the machine is on the handbrake. If the bolts stick, it will take a lot of force, so make sure the vehicle will not move.

    with lever

    Often, wheel wrenches have a short handle, which does not allow you to develop sufficient force. The easiest and safest way is to extend the handle of your key. This will make it possible to create a very significant effort. In the absence of a wrench with a long handle, you need to put a metal pipe on the handle of your wrench.

    with leg strength

    If your arms aren't strong enough to loosen bolts, use the strongest muscle in your body, your legs. To do this, put the wrench on the nut so that the handle is parallel to the ground. Carefully place one foot on the key so that it spins counterclockwise. You can also lean on the car with your hands and stand on the key with both feet. Then jump a little. When the nut has moved, unscrew it as usual. Be very careful. The key is not the trampoline. You can not kick the key or jump on it so that the feet come off the handle. Avoid sudden loads on the key.

    with hammer or mallet

    Take a hammer or mallet and hit the handle of the wrench, in some cases this is great for loosening stuck nuts. In extreme cases, even a stone can be used instead of a hammer. Avoid slipping as the bolt and wrench may be damaged. It is necessary to apply short well-aimed blows.

    with torque wrench

    Use a torque wrench when tightening bolts. If the wheel bolts on your vehicle are too tight after the last removal of the wheels, use a torque wrench to secure the wheels to the torque recommended in the manual.

    with chemicals

    Chemicals should only be used as a last resort. If the bolts are overtight, apply Liquid Wrench or PB Blaster to the bolt. To apply the product exactly on the bolt, use a watering can with a thin spout. Wait ten minutes and try to unscrew.

    If grease gets on the brake disc, what should the driver do

    Lubricant on the brake disc can increase braking distance and cause an accident. If liquid gets on the disc, clean it with a solvent and a clean rag. If oil gets on the pads, you will have to replace them.

    Pro Tips

    If the car's wheel is stuck to the hub, loosen the bolts and try driving the car for a short distance. This force will pull the wheel off the hub.

    How to unscrew the bolts on the wheel

    No one is immune from the fact that you have a flat tire on a trip. The main thing is to notice this in time and prevent the rubber on the wheel from “jamming”. After all, every self-respecting motorist has a spare wheel and a tool for installing it. But first you need to remove the punctured wheel, and to do this, unscrew the mounting bolts.

    Before starting work, secure the vehicle against forward/reverse movement. To do this, turn on a lower gear, put the car on the handbrake and install two corners - anti-recoil - under the front and under the rear wheel. Do this so that one prevents the car from moving forward, and the other back.

    Position the jack in the location closest to the wheel you are about to remove. Raise the car slightly until the jack is loaded.
    Use the wheel wrench to start loosening the bolts by turning them ½ -1 turn.

    Raise the vehicle with a jack until there is a free space of 3-5 cm between the wheel and the surface where the vehicle is standing. After that, unscrew all the wheel bolts to the end. Remove the wheel.

    The work does not always go smoothly, sometimes unforeseen difficulties arise - the wheel bolts do not unscrew. There may be several reasons for this:

    What should I do in this case?

    The most reliable thing is to entrust the work to specialists. Take pity on your strength and nerves, and if some bolt does not want to unscrew, put the turned out bolts in place and go to the service station.

    If you are used to overcoming difficulties on your own, try using a few tricks to unscrew the "naughty" bolts.
    Step One: Lubricate the bolts with WD-40 penetrating lubricant or kerosene brake fluid. To do this, soak a rag with them and put them on the bolts. Hold for a while and try to break the bolt loosely, i.e. turning it one way or the other. You can lengthen the wrench handle, thereby increasing the torque.
    Second trick: heat the bolts. It is better to do this with a gas burner. Before heating, tap the bolt with a hammer. Heated bolts try to unscrew.
