Quick Answer: Is Over Torquing Lug Nuts Bad?

Is it OK to drive with a missing lug nut?

If you are missing a lug nut, it is important to have it replaced as soon as possible.

It is potentially dangerous to drive around with a missing lug nut because of the extra pressure exerted on the wheel.

This pressure can damage the wheel bearings, studs, and cause other lug nuts to fall off..

How much torque does an impact wrench need to remove lug nuts?

Yes, a good quality electric impact wrench will have a nut busting torque in the range of 500 – 700 ft lbs. More than enough to cope with auto lug nuts.

How many ft lbs should lug nuts be?

And when you look at that, and realize that the average torque required on a lug nut, to hold the wheel on, is 80 to 90 ft-lbs, well you can imagine how over-tightened some of these lug nuts are. Now that’s a problem because it almost guarantees warped brake rotors.

Do screws loosen over time?

Over time, the threads can deform inelastically, reducing the amount of normal force available to create friction between the screw and the hole. As a result, it becomes easier for vibrations to rotate the screw. … This is why screws will often loosen over time to a point and then stop.

What happens if lug nuts are over torqued?

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 often should lug nuts be replaced?

every 10,000 milesAnd of course wheel nuts should be re-torqued at regular maintenance intervals or every 10,000 miles to account for any changes in clamping force.

Can I re torque my own tires?

Professional car mechanics can re-torque your tires, but if you prefer to take the DIY route, it can be done. You will most likely need to have a torque wrench that can identify how much force you’re using to avoid over or under-tightening the lug nuts.

How do you put lug nuts back on?

Push the wheel home on the hub and using your socket wrench, tighten the wheel nuts just enough to hold the wheel snugly. Work in a criss cross pattern, tightening the nut that is almost directly opposite from the nut that you just tightened.

How tight should Lugnuts be torqued?

Run the lug nuts in with your favorite tool until snug, but no more. Tighten the lug nuts in a star pattern twice, smoothly applying force until the wrench clicks, but no further.

Is it necessary to re torque lug nuts?

Lug nuts must be torqued to the manufacturer’s recommended values, and they must be re-torqued to those values after driving approximately 50 to 100 miles on your new tires after the tire service. Both under and over tightening can be dangerous.

What happens if you don’t re torque tires?

Both of those situations can be dangerous. If the lug nuts are too tight, the bolt head can come off the lug nut. If they’re too loose, the bolts could fall out, and your tire could come off. While both scenarios are unlikely, they would both cause some serious damage if they were to occur.

Is it OK to lubricate lug nuts?

But experts tell us not to use any lubricant, including anti-seize compound, on wheel studs or nuts. The tech folks at Tire Rack state: “Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. It is important NOT to lubricate hardware threads or seats.

How tight should you tighten screws?

We suggest you tighten the nut, bolt, or machine screw by hand until it makes contact with the washer or the surface of the workpiece. Then, using an adjustable wrench or a socket wrench, make a consistent number of turns to ensure that all the bolts have the same torque.

Why is over torquing bad?

When you over-torque the lug’s you do the same damage as any other over-torqued bolt, it stretches, possibly gains stress fractures and is no longer certified for its load rating.
