What are you torquing them too? What size socket are you using? Stock lug nuts?

 

not really torquing them just using impact maybe over tightening with impact just seems weird never had issue on other vehicles and stock lugs and studs

 

Ohh 21mm socket

 

I'd say go out and buy a new 21 MM impact socket and make sure it is only 6 sided. Sounds like you may be using a 12 sided one that is likely worn out at this point.

Also. most aftermarket lugs are 19mm, make sure the previous owner did not change them out.

 

I've owned vehicles that were notorious for galling or stripping wheel stud threads - and no amount of fiddling with torquing specs or procedures seemed to help.

As a last resort, after installing brand-new studs and nuts, I'd use a VERY tiny amount of anti-seize compound on the threads, taking care to:

1. Avoid getting any of it on the working face of the nut (the part of the nut that snugs up against the wheel). Keeping this surface "dry" helps prevent the nut from eventually working loose, due to the reduced friction between it and the wheel that would otherwise occur in the presence of anti-seize.

2. Reduce the final tightening torque somewhat (roughly 20 percent). This helps avoid overstretching the studs, which could otherwise weaken them. (Anti-seize reduces the amount of torque required to maintain the same amount of clamping force. So, if you're using the same amount of torque after applying anti-seize as before, you're probably overtightening the nut.)

Of course, it's NEVER a bad idea to occasionally re-check your lug nuts for adequate tightness.

 

Def stop using the impact as only device. Use a torque wrench and torque to 95 lbs/ft. And as others said, get a good, 6 sided 21mm socket for them. Should alleviate your problems. You can throw a little anti seize on there but I don’t. And I’ve never (knock on wood!) stripped one.

This.

 

I use a torque stick to tighten the lug nuts. I'll put the lug nut in the end of the torque stick (100 ft/lb) and begin by threading it on by hand initially (as well as the other lugs). Then I'll use the torque stick on an impact gun in a criss-cross pattern to tighten them up. I've never run into a problems with them.

 

Torque sticks are better than just using an impact (if used properly) but still not as good as a torque wrench. Can still end up with warped rotors. There’s a reason you don’t use torque sticks on head bolts....

 

Wasn't that exactly what they were invented for? Assembly line machine torque extension bar used in 70&80's (now obsolete)

 

there was a YT tool review channel (may have even been AvE) that found that torque sticks 'need' to be matched to teh driver. He found not only is there a mfr tolerance (posted by mfr) but he also found that different mipac guns (both air & batt) gave different measured clamping force... so if you're new to a stick, I would verify with a torque wrench that you don't overdrive the lug (which is why for hobby-ists I suggest torque wrench every time) until you get used to its feel.

 

You’re not supposed to use anti seize on torqued bolts as they over tighten easily, run the nuts on until they seat and properly torque them and although I own an air wrench it mostly always resides in the drawer of my tool chest.
I am on my almost 50th vehicle and have never broken or stripped a wheel stud, the air gun isn’t your friend, it just speeds thing up and in the end costs much more time, effort and money.

As I lost access to my friend's shop and started doing work in my yard, I switched from air impacts to electric tools. Currently, I use a 18v Ryobi 1/2" drive impact gun rated at 300 ft/lbs for doing lug nuts. I use an Accutorque torque stick to tighten/torque the lugnuts in a criss-cross pattern and double check when I'm done with a Snap-on torque wrench. So far, I haven't come across any loose lug nuts, but, I agree, it's always a good idea to double-check!

 

Shop access was a nice thing for you I’m sure the battery gun is a nice tool but be careful as it can do just as much damage as an air gun. If you’ve ever gone to Costco the only use a torque wrench, no air gun or sticks when installing the wheels back on. Again it may take a little more effort and time but you’ll never have any issues like this again. My faith is on the wrench over the stick, have you ever seen a head being put on with and impact gun? When over tightening a bolt you’re stretching it and can also snap and have a catastrophic failure, surely you’ve seen vehicles on a highway that suddenly lost a wheel. May that never be you or any other member here.

Most head bolts are torque to yield and I don't use impacts on head bolts! I've spent 16 years working as a Nissan Master Tech have 30 years of automotive and truck mechanical experience. I think I got the "putting on a wheel" thing pretty much down pat!
::wink::

 

I crack them free with a 24" breaker bar, spin them off/on with a cordless drill and tighten them with a torque wrench.

My truck is a 2010, have had the wheels off a dozen times or more for various reasons. No issues.

 

Technically, "former" Nissan Master Tech. I left Nissan in October, 2003. I stopped doing full-time mechanics in 2007, but continued doing it on the side since then. Having been in the car business since 1984, minus a couple of years driving tractor trailer, I finally got burnt out and began to loath working on cars! I picked up a job as an officer in the Dept. of Corrections and have been there ever since. My knees no longer hurt, my fingers no longer have sharp pains in them and my nails are clean...plus, I get to work in air conditioning instead of sweating my butt off over a hot engine in the summertime!

 

Proper hand held torque wrench > impact gun

 

I have a set of these from my mechanic days

mine are MATCO (I think), but most work pretty well

I have seen them sold individually as well

but hand held torque wrench is the best like RAINE says

 

Ya think? Obviously you are over tightening!

 

I put anti-seize on the threads. Also, not a good idea to remove the nuts when the wheel is hot (from braking).

I never use anti seize.
I use impact wrenche all the time! Never stripped a stud. Keep it below the torque spec, finish with torque wrench.
I keep a Milwaukee impact in my truck.
Don’t have time to wait for wheel to cool down. I use Kevlar gloves. No torque wrench, no time.

 

NEVER use an impact gun on lug nuts to tighten them. Always use torque wrench to tighten to about 70 to 80 Ft pounds. Impact guns over tighten making it impossible to get off if you have a flat away from home..Plus the probable warping of the rotors because of unequal torquing of lug nuts using impact gun. Jerry...

 

Torque spec for stock wheels, is 98 ft.Lbs., or around there.

 

There isn't a single shop out there that uses a torque wrench to put on tires, maybe there is but let's be honest a couple seconds using an impact gun and you're usually there. I just rotated my tires last night, used my electric impact gun to take off and put on all tires. Dropped the truck from the stand and checked each lug, they were all about 70-80#, I did take my torque wrench and finished them all by hand.

 

Yes there is, there's even some chain tire shops that do it simply by request. All the America's Tire shops I've been to automatically hand torque lug nuts for any vehicle that rolls in with aftermarket wheels.

That "couple seconds using an impact gun" is the difference between shops getting the job done fast vs. shops getting the job done right.

 

My good friend who owned a brake and alignment shop. Always torqued the wheels. He is in his seventies and leases the shop.
Over tighten and it will distort the rotor.

 

Most shops that I've worked in (that includes Nissan dealers) use impact guns with torque sticks.

 

Depends where you're at ::wink::
