lug nut bolts keep breaking

Anti-Seize is a definite NO NO!

Impacts are perfectly fine as long as you use a torque stick with a lower value than the specs for the vehicle AND you have the impact on the lowest tighten setting.

 

Try turning the lugwrench counter-clockwise.

 

Just broke one of my lug nuts.
I'll man up and share how just so someone else doesn't do it....
I used the stock lugwrench and stepped on it. One or two bounces was all she took and SNAP!

I've been removing lug nuts this way for years (I'm 46) and never had a problem, but one finally found me.

Do NOT use the factory lug wrench for anything but an absolute emergency.

That is all.

 

That is what caused it to break. Stepped on the lug wrench and bounced! You should apply pressure to the end of the tool with one hand while supporting the other end at the nut with the other hand. Feet should never be used. Or if you are a woman call a man or AAA to change the tire for you.

 

if you had to jump then something was wrong, I use a 17" breaker bar and it takes very little effort to break them loose

 

This man nailed it right here on the method to properly mounting on these Yota rims and lugs without damaging anything. That's the way I have always done it on my own Taco and it has yet to fail me. I make sure the wheel is nice and centered then I'll start installing a lug nut. I get to installing the second directly across from the first one I installed then I lightly hit them both with an impact to make sure they are in and fully seated. After that I install the remaining four then hit the very last one at full impact then cross tighten the rest of them to torque. This method has never failed me, nor any other vehicle that had the correct fitting lug nuts/rims combo in my 12+ years of working on vehicles, ever.

 

My company uses anti seize on every vehicle and every machine. We have about 20 trucks and drive to Texas every other week and have never had a problem with lug nuts losening. We make sure we retorque after 100 miles. If we don't use anti seize, the lug nuts can be a bitch to get off, especially if it's a older vehicle with a lot of miles that the wheels have been taken off a bunch.

 

The secret is not to over torque them. Always go by torque specs. Over torquing results in stretched stubs an then they break.

 

Question: Anti seize or no anti seize?

Answer: Some do and some don't base on the replies.

I guess it is up to the owner huh? I personally don't use anti seize and no impact gun. I torque my wheels one by one by hand to the toy's specification when I'm at home. If I'm on the road, I'd put enough force to keep it tight for me to get home safely then I'd torque it. Never a problem all of these yrs.

 

No anti seize.

30 weight oil few drops.

Torqued to spec.

 

I use anti-seize AND an impact gun, to run the lugs on. Then I torque them at 75% of the nominal value, to allow for the increased lubrication the anti-seize provides. I haven't broken a stud in decades...but I do tend to keep spare studs and lug nuts on hand for when I find a bad one.

It's pretty easy to go over spec with a tire iron use a torque wrench 85lbs isn't alot

 

I always just use an impact gun with the compressor set to 90 psi.... Never had a problem

 

The general consensus here is that if you live in the Midwest or by an area that has many contaminants, road salt/grime use anti seize. If you live in a generally clean area and generally maintain your stuff at every oil change you will be fine.

 

40+ yrs wrenching everything from aircraft to Zambonis. Quarry machinery, jumbo trucks, rock crushers, salt water boats, large machinery dating back to the 1870's.

For lugnuts:
Antiseize always.
Use air just to snug them.
Torque wrench to specs.

Never lost a tire. Never broke a stud I'd previously gotten free.
If getting a stud loose seems too hard, I break out the hot wrench.
Little heat on the nut, cool rag on the stud, and off it comes.

Before removing a wheel, sometimes I'll hit the threads with a wire toothbrush and some PB if the is a lot of junk built up.
