How Many Foot Pounds Should I Torque For Lug Nuts?

How many foot pounds of torque do I need for tire lug nuts?

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..

What happens if you don’t tighten your lug nuts?

If the lug nuts or bolts are loose, the wheel will not be held snugly against the hub of the vehicle. When the vehicle is driven, the wheels will shake. The shaking will be felt in the steering, and likely throughout the whole car.

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.

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.

What is a good torque for an impact wrench?

1200 ft/lbs.The average torque for 3/4 inch impact wrench is about 1200 ft/lbs. As stated before, it is more than enough for even the most substantial tasks.

Can I use a torque wrench to remove lug nuts?

It takes a higher torque to loosen a bolt or nut than it takes to tighten it, even if it has just been torqued to specification. Yes, you could if you do NOT value the torque wrench and have no regard for its prior accuracy. However, a tradesman would never do that, neither would they ask such a question.

How much torque can a 1/2 drive take?

150 ft-lbs will break a 3/8″ drive usually and about 300 ft-lbs will break a 1/2″ drive. These are on regular breaker bars that are partially hollow and have the little ball in the space of the head to hold the socket. A SOLID 1/2″ heat treated impact rated drive anvil will go up to about 1200 ft-lbs.

Is 450 ft lbs enough?

450 ft lbs should be enough for most, if not all suspension work, and it will do most everything else too, unless you live in the rust belt, or you’re working on large machinery/trucks. The smaller impacts would do 90% of what your asking of them in that regard, and it wouldn’t be such a heavy, unwieldy beast.

How many foot pounds does it take to tighten a tire?

The truth is, the average foot-pounds of torque needed to keep today’s wheel fasteners safely in place is between 65- and 80-foot-pounds. Again, that’s on average. To many of us, this doesn’t seem like enough torque to keep the tire/wheel assembly from leaving the vehicle on which it is mounted.

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

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.

Do all torque wrenches click?

Some have a dial to set the required torque, but the indicator doesn’t stop applying force automatically when torque is reached. They may have a visual signal such as a digital reading or an audible beep or click. … A click torque wrench can be preset to a specific torque level.

Tighten the lug nuts with a torque wrench to the manufacturer’s recommended settings, which is usually around 90 foot-pounds. Tighten the lug nuts in a star pattern, alternating from any lug nut to one that is directly across from it. Recheck the tightness of the lug nuts after the vehicle has been driven 100 miles.

What size torque wrench do I need for lug nuts?

½-inchAs with socket wrenches, you can handle most major repair needs with a ½-inch wrench. (That’s the size we use in the Car and Driver test garage to torque lug nuts.)

How tight should lug nuts be by hand?

Snug them down and tighten pretty much as tight as you can without blowing something out, but not so tight you can loosen it with the samw equipment. Then drive, carefully, check for loose nuts every 25 miles or so, and dont drive fast. until they break off, then back off 1/4 turn.

How tight should lug nuts be without torque wrench?

Normally, once all the nuts/bolts have been started and made contact evenly with the wheel, no more than a 1/4 or 1/2 turn is sufficient torque. A little too much is better than a little too little.

Is it OK to hand tighten lug nuts?

If you simply want to re-tighten the fasteners, that can be done one at a time on the ground. Step 3: Install the nuts by hand. Install the wheel lugs by hand. … Push the wheel home on the hub and using your socket wrench, tighten the wheel nuts just enough to hold the wheel snugly.

Do I really need a torque wrench?

Torque wrenches may seem like a luxury you don’t need, but they are actually used for a very specific, very important reason. They are versatile tools that can be used for multiple applications. The most common and prevalent use of a torque wrench is for changing rims.

How do you know how much torque?

Car manufacturers specify a proper tightening level, a torque value expressed in foot-pounds, that can usually be found in your vehicle’s owner’s manual. Torque is a rotational force applied around a point or, in this case, a nut. Put a 1-foot-long wrench on a nut and apply 10 pounds of force to the opposite end.
