wheel torqueing on tv, what do you odo?

[Drey]

I shoot them on with an impact, but I dont torque them down with it. I use a 4 lug for that, check them every 10-20 miles for around 300 miles. Havent had a problem with it yet. Used to just use an impack...had my 4x4 hub save my a$$ right after I got all the body work on my truck done. that would of sucked to that tire mangle pristine sheetmetal that was just painted

13 years wrenchin most in tire stores I just use a impact myself but running a store and working with bunch of idiots everyone torqs every wheel every time or you are outa here. I have a good technique and trust myself to put them on pretty evenly tight. the only ones I worry bout is the tiny Geo studs. everyone breaks them all the time.

have you ever seen a twisted set of splines or a twisted socket extension. That is loss of torque. It is a minimal amount but still a measurable amount.

For those who use a torque wrench, what torque setting do you use?

Torque wrench every time for me too...88 ft-lbs on my 70 k5.

88 ft-lbs? been a while since I looked at the spec for a 1/2 ton, is it really that low? I know 1 tons(D60 and 14 bolt) are 110 or so.

Yes I have, and after those splines twisted, how much torque do you think was then transfered?

A quick google turned up a couple things.

As long as the extension is in the same axis as the nut/bolt being tightened, there is no change.

1 "squeak" with the four way

When I had a 1/2 ton burb it was mandatory to use a torque wrench other wise I was replacing studs evertime I took a tire off. That or I would get this strange wobble letting me know my studs were sheering and I had about 1/2 second to stop before I was chasing a wheel down the road. Damn 7/16 studs

Which is why I put 9/16 on my 6 lug. Not as much as 8 all the way around, but beef nonetheless. I use a 4 way on all my stuff.

ram them on, but carry a breaker bar so i can bust them loose on the trail if i need to

I use the tool that vehicle carries for changing tires to tighten them. That way I know I can get them loose. I do keep the threads in a thin film of anti-seize so that they don't rust on.

..

Refering to an extension reducing the torque applied to the fastener

This is a myth. Think about it. The main reason for loss of torque I have heard is that they twist, therefore not applying all the torque applied to said nut/bolt. Well if they do twist, the business end is going to have the same amount of torque applied to it as the wrench end once any "slack" in the extension is taken out. Is there less torque applied to a wheel than what is coming out of the differential? Same principle.

While it true that twisting an extension doesn't change the torque applied to the nut, most impacts do not apply a constant torque. They, ahem ( ) apply an impact. So the extension ends up acting as a damper, which means that the full impact force does not reach the nut, which means that they don't get torqued to the full possibility of that impact gun.

Thanks for adding that, I didn't read it as being used with an impact, just with the torque wrench. I hate when people spew crap out their butt with no fact behind it. All it does is misinform people, thousands in a case on a board like this.

Now back to your regularly scheduled program.

when was the last time you used an extension on a torque wrench and didn't get some deflection though? Can't say I ever have...

 

[Slapperbar]

Sticks to 120# on a 3/4T 'Burb.

 

[diesel4me]

what I do...

I use either a 4 way lug wrench,or the "stock" GM lug wrench with a 2' pipe on it to loosen and tighten my lug nuts..that way I'm fairly sure I can bust them loose later if I have a flat!..

My flea market air gun wouldn't twist the foreskin off a misquito!--I have to break the lugs loose by HAND before it will remove them!..but if I use it to tighten them,I always use the 4 way or other wrench to finish tightening them..I avoid using an impact on aluminum or mag wheels..

My friend who has run a tire and alignment shop for decades always used the impact --he claims he can "feel" the torque ,and is confident they wont be too tight or too loose..he claims he'd rather have someone call him and ream him a new bunghole because they could not get the lugs loose when a flat tire occours,than have a lawsuit over a rim that fell off and killed someone..

Everyone should just install a York and have onboard air, then you don't worry about overtightening and can just impact them off
