Is Over Torquing Lug Nuts Bad?

Is over torquing lug nuts bad? Over torqued nuts can cause problems too. It stretches the studs reducing the tensile strength which can cause them to snap.

How tight should you tighten lug nuts?

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.

What happens if wheels are over torqued?

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.

What happens if you over torque axle nut?

It's possible to damage the wheel, rotor, and hub assembly. The wheel can come off if over-torquing the nuts/bolts is done.

Can over tightened lug nuts cause vibration?

Overtorquing the lugs will cause a vibration via rotor warping, but only during brake application, it will not cause a static vibration, unless the warp is so huge that braking would be dramatically effected. The concern is not over over-torquing so much as it is how even the torque is.

Can you over tighten lug nuts with a torque wrench?

The improper use of tools, such as impact guns, can result in the same dangerous outcome or worse, as over-torqued lug nuts can cause permanent damage to them. Many of these situations are the result of using an impact wrench to tighten hardware.

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.

Why do my lug nuts keep coming loose?

Where fasteners are to blame, several factors can cause nuts to work loose. Excess paint, rust, scale or dirt between mating areas of wheel end components will lead to low clamping force. Fractured or worn out nuts with deformed threads have also been linked to loss of sufficient clamping force at the nut flange.

What can happen if too little torque is applied?

Insufficient torque

When you apply exactly the right amount of fastening force, you can rest assured that the bolt will transfer the 'hits' as well as the load of the belt to the bulk of the engine, which will absorb them. This, in turn, will lead to incorrect belt tension and, eventually, to belt and/or engine damage.

Do bolts weaken over time?

The hydrogen embrittlement time to failure is typically within 48 hours. The break will almost always be directly under the head of the fastener and not in the threads. This type of failure, while not common, almost always occurs in very high strength fasteners, or case hardened fasteners that are electroplated.

Can you torque without a torque wrench?

Can you over tighten an axle?

No. Over tightening won't put more of a strain on the bearings in this sort of design. You should've torqued those nuts down quite a bit.

How much torque does an axle nut need?

Also, in almost all cases, use a new axle nut. with no more than 15 to 20 ft. lbs. of torque while rotating the wheel to make sure the bearings are seated.

Can you reuse axle nuts?

The shop manual warns not to reuse the axle nut, so I trotted off to the parts store for a new one. I'm referring to the special nuts on major components like axle shafts and ball joints where a lost (or loosened) nut can cause accidents, even fatal accidents.

Can different size lug nuts cause vibration?

Registered. Okay, the Eagle F1 (junk) tires needed to be replaced on my 2001. Car drives straight, no wheel shake, doesn't pull, never had a problem even at very high speeds.

Do you have to jack up your car to tighten lug nuts?

3 Answers. Nope, doing it with the wheels on the ground if fine, no need to lift the weight of the wheels. It's easier that way because the wheels can't turn while you are torquing the lugs.

When should you'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.

How do you get a torqued lug nut off?

  • 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 should you torque lug nuts?

    When installing the wheels on a vehicle after servicing, it is important to torque the lug nuts properly. Lug nuts that are not tightened correctly can ruin wheels, affect rotor runout and can be deadly if the wheel comes off or studs snap. Over-torqueing the lug nuts does not affect runout immediately.

    What happens if you don't tighten lug nuts?

    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.

    What happens if you don't tighten wheel nuts?

    If the screws are not tight enough, they can come loose whilst driving. If the wheel bolts are too tight, the threads might get stripped or damaged. And this is where the torque wrench comes in. Using a torque wrench enables you to tighten up the wheel bolts to a specified torque.
