Sooo... I noticed I am missing a lug nut (2009 FX4) guess the guys at Grismers didn't torque it right when they rotated my tires... grrrr.

Question, where can a man find a lonely lug nut to match the others?

Thanks in advance.

Dealership for sure. Take your wallet with you. The chrome ones are about 12 bucks each

 

Same thing happen to me. I took the paperwork back to the dealer that worked on it last. Asked if they had a lost and found. They were the last one to touch them. Left with a new one and no cost.

 

I have yet to see a dealer that uses a torques wrench.
150 ft/lb for F159 lug nuts

 

Or any shop for that matter. Just hammer them on with an air impact is the only way I've ever seen it done.

 

In a related question , how many of you put some goop on the threads so the nuts don't rust on solid ?? After a couple of experiences with almost impossible to remove nuts [even with power wrench] I now coat the threads with goop .I've never had a problem with it. One of the lessons from living in the rust belt !

 

They warn against putting anything on the threads. They back off and loose the torque.

 

Discount i know for sure torques.

Hand start them, impact to snug them up, put car on ground, torque to appropriate setting (that number should be on your paperwork), then circle check to make sure they are torqued properly.

If they only impact them, when you get home bust them loose and re tighten them yourself. Nothing is worse than getting a flat and not being able to get the lug nut off w/ the crappy wrench they give you w/ the spare b/c they were over torqued

 

Americas tires dose the same and the sears auto shop here dose it to but never ever seen wheel works or big o tire do it! and i don't know about my dealer they wont let me see in the shop!

 

They shops are most likely using the torque stick installed on the impact gun.

I have a set work pretty well. Next tire rotation I need to verify with the tq wrench to make sure they are still in spec.



For the side of the road I always keep a real jack and extendable breaker bar in the truck. Don't cost much, and gives you a real breaker bar and double end socket. Never used it on my truck, but have used it a few times on other people' cars.

 

How does a torque stick work?

 

Google.

I'm not a fan of them, they might be great but i'd rather have a torque wrench to verify my results.



Wouldn't the torque out put vary depending on the impact and air pressure supplied?

 

I don't believe so. My understanding is the just twist more once you hit their limit. While they are far better than nothing, a torque wrench is far better. At least with a torque stick, you will not have one lug at 200 ftlbs, and another at 120. At least they will all be in the same ballpark. My dealer uses them.

 

I was reading that they can vary up to 25% and also vary upon how used they are.


How can PSI not have affect on it? The impact will either not have enough power to torque to the torque sticks setting, or it will have enough to max out the torque sticks limit and over rotate it.

I refuse to use them, i found them to be worthless and terrible.

For example, a 3/4 ton IIRC is around 150 ft-lbs. Use the torque stick, then check with a torque wrench, doesn't even turn before it clicks. Right there is a dead give away it's over torqued which is a good way to destroy wheel studs.

 

Gun to gun can vary.

There are directions for setting the gun for use with them if they are out of wack. Most guns are plug and play, but it needs to be verified
