Lug Nut Torque?

[FlimFlamMan]

Anyone know what the torque should be for our lug nuts. Specifically 17" oem steelies or alloys?

I've searched around and havent found any info.

Thanks in advance,

Lug Nut Torque

Ok, sorry for the stupid question but...

I just got an impact wrench and was gonna rotate my tires this weekend. To get 90lbs, do I set the regulator on the compressor to 90lbs and then hit the lugs with the gun until they don't turn anymore?

You need to buy a torque wrench and read the instructions.

I agree with HemiHunter. Invest in a torque wrench.

Agree again. Torque each to 30, then 60 then 90. Go in a crossing pattern line a star, not one after the other in a circle.

Feel free to use it to take the nuts off, it'll save some labor. Two reasons not to use it to put them back on.

1) Too easy to over-torque the nuts.
2) If you get one cross-threaded and hit it with the air wrench, you'll be relplacing a stud.

Regarding number 2 above. You can use the air wrench to do most of the turning. Most impact wrenches have a little knob that allows you to turn the tourque way down. So, start the nuts by hand, use the wrench to get them snug against the wheel, then finish the tightening by hand. I just do it by 'feel' and have never had problems, but a torque wrench is nice if you don't want to guess. Use a criss-cross pattern as suggested above.

A torque wrench is a friend worth keeping around. If you get one, make sure it is top quality. Mine is a Snap-On QJR2100D. I bought it in 1985. Don't drop it. Don't yank it like a breaker bar. Get it recalibrated periodically. I use mine on everything from lug nuts to spark plugs.

Well since you just got the gun and WANT to use it. I would just go purchase a 90flb 21mm torque stick. It's what most techs use including all that I work with. That would save time and money. Torque wrenches are nice but are not needed to torque lug nuts. The torque stick looks like an extention but is designed to torque lug nuts. They are cheap. Torque wrenches are VERY expensive. But if you plan on doing some major overhauling like heads or what not, I would deffinetly get a torque wrench. And yes, always go in a star or "criss-cross" pattern when tightening lug nuts. This is just how I do it. You can do it either way.

And if you can't get them snug enough with the 600 ft-lb impact wrench, you can get the last couple of turns with a 16 lb. sledge and a slugging wrench.
