What happens if I over torque my wheel nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud. Insufficiently tightened lug nuts can come loose, with catastrophic consequences.
How do you remove an over tightened lug nut?
Loosening Tight Lug Nuts
- A breaker bar. Oftentimes, a regular lug wrench or tire iron alone isn’t enough to do the job.
- A mallet or hammer. If you don’t have access to a breaker bar or pipe, a few blows from a rubber mallet or hammer to the handle of the lug wrench might do the trick.
- Penetrating oil.
- An impact wrench.
Why do tire shops over tighten lug nuts?
Most shops over-tighten them for 2 reasons. 2. They’re too lazy to come back with a torque wrench. Either way, it sucks and can REALLY piss you off when its time to take them off…
What will occur if a wheel is tightened beyond torque specifications?
If the Lug Nuts are tightened beyond their design limit, the wheel stud or bolt can permanently stretch (fatiguing beyond its designed elastic range) or even break during installation.
Can you use WD-40 on wheel nuts?
WD-40 should not be used on lug nuts whether to try to remove them or to clean off rust. By applying oil, grease, or an anti-seize preparation to the threads, you run the risk of over-torquing them when you tighten up your wheels. WD-40 tends to be more of a band-aid fix than anything.
How does a cheater wrench work?
The Cheater Wrench utilizes gears to multiply torque. As you rotate the handle, several gears inside the wrench act together to amplify the force. You can see this by rotating the handle and then watching the impact. After dozens of turns, the impact has only rotated one revolution.
Is over tightening lug nuts bad?
Over tightening can warp your rotors. You’re never supposed to use an impact gun to put lug nuts on because there’s no way to accurately control the torque that’s being applied. Mechanics do it is because it saves time.
Can you over tighten lug nuts with a tire iron?
Well, if you figure that the tire iron is about a foot in length and you apply ~100 pounds to the end of it, I am pretty sure you will achieve the 98ft*lbs of torque required. Heck, you may even be over-torquing them.
What can happen if a wheel fastener is over tightened?
Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
How much torque is too much?
Most 2WD road cars – even with large grippy tires – can’t handle more than 400-500 lb/ft of torque. AWD cars can handle as much as 600 lb/ft without losing traction.

Can a overtightened lug nut be repaired?
The repair is not difficult. If it is evident that the nuts were severly overtightened the studs and nuts should be replaced even if they don’t break when twisted off but it sounds as though they will break when enough torque is used to turn them. Pulling a hub isn’t always so easy either.
Can a torque wrench be used to loosen lug nuts?
The torque wrench is used to tighten only. Nobody cares about break free torque and the wrench isn’t designed to handle excessive leverage. A length of pipe over a breaker bar and 6 pt socket will remove the nut. Then carefully inspect the threads for damage.
Why are my lug nuts stuck on my Rims?
I’ve also seen situations where the stock, unchromed alloy rims had stuck lug bolts, probably due to overtightening. Putting the car on the ground, and using a breaker bar with a pipe usually broke those free. In a few instances, I’ve seen very powerful 1/2″ drive air impacts actually sheer off the lug bolt heads.
