Lugs/Studs

Lugs/Studs

So I decide to rotate my wheels today. One lug from both front wheels decided to be stubborn. So I wait for the wheels to cool down. After 45 or so minutes I come back and was able to take them off, with a bit more force than the others.

I try to put different lugs on the studs that gave me problems and it was not working. I guess the studs are now broken/misthreaded (any other term for it?).

So now both of my front wheels only have 3 lugs on. I know its probably not safe but what am I to do until I get them fixed? How hard is it to actually replace these things?

All you have to do is take a hammer and do some really really hard banging. They should pop out.

its very simple to replace wheel studs. as long as your front rotors are floating all you have to do to make it 100x easier is to pull the caliper and rotor and its all right there in front of you.

If the stud is not completely broken off I suggest you just run a M12X1.5 dye through the stud to rethread it.

what!? really they have those? :thumb:

They are not completely broken. I didnt even know they can be repaired. I will research on it. Any DIY links?

thats what you need, just run it through the stud once with some oil (wd40 is fine) and you're done. You could either use a die tool or just a 1" socket and a ratchet.

If you do have to replace it, getting the old one out is easy, pressing the new one back in, not so much.

Make sure to wear ear plugs. Bangin on them is very loud and takes a couple of really hard bangs for those suckers to come out. You will hear ringing sound in your ears if you don't wear ear plugs.

I hope I don't have to replace them then.


JspeXAE102: So all I have to do is get this, some WD40, and run this through the stud like an ordinary bolt/lug?

yep, except back it out a bit every 1 or 2 turns to evacuate the metal shavings. just keep it soaked in wd40 to keep eveything cool and lubercated.

A can of pressurized air helps too.

Thanks guys. So that link takes me to the one I NEED for my car right? Ill buy it now and wait for it to come.

When you do this rethreading you should take some pics and post up a DIY on here for people with future problems

Just a suggestion

I intend to do that kryptickarma.

i wouldnt suggest rethreading a wheel stud. a replacement stud is cheaper than a die, and the piece of mind that a complete wheel stud offers over a damaged/repaired stud tremendously outweighs not replacing the wheel stud.

once you run it through a die, it will never have the same strength as it did before. remember, you arent truing the threads in this case... you are re cutting them.

id hate to see you make a thread about how your wheel came off when your studs failed.

but just one out of 4. I see your point tho.

If only one or two threads are messed up he wouldn't be cutting new threads throughout the entire stud, mearly cleaning/re-cutting the damaged parts. Replacing the front wheel stud on a FF is actually much more labor intensive. In order to do it correctly the entire hub must be pressed out.. although most people do it the half assed way which requires trimming a slot in the brake dust shield so the stud can be removed from the back.

he said 1 stud on either side... not 1 thread.

i just dont feel personally comfortable using a "repaired" wheel stud that needs to hold ~80lb/ft of torque while spinning ~20,000rpm. for the price and ease of the install it just seems a no brainer.

but good luck with whatever choice you make

it would depends on the extent of damage, but damaging just 1 thread would be enough so that the lugnut wouldn't re-thread.. which is usually the case I see. If the damage was much greater the stud would've broken off during removal.

Thats why I'm thinking just one or two threads are crossed or bent, and I agree lAresl should use his best jusgement before proceeding.

I agree with both points. If it's just a thread or two that is damaged, re-cut it and you're on your way. If it's more than that, pull it out and replace it.
HOWEVER.
From personal experience just a couple of weeks ago, without taking the hub apart, pressing a new wheel stud in is... for lack of a better phrase... a bitch.

We destroyed one of vortex's old lug nuts sucking that thing into place.

That made my day.

I know on one stud, I can easily use my fingers to turn the the lug up to a certain point, around two or more rotates before actually locking it into place. The other stud, just getting into the first two rotates, I already need to apply more force than usual.

That being said, I might just buy the re-threader and play with it then have the peeps from Toyota fix it. I hope one of my uncle's co-workers can give me a better price.



Here in the first pic, you can see where it actually is broken. The lug slides through until that mess.




Here in the second pic, you can see that the stud has 2 different colors O.O" I think a piece of metal got trapped between the lug and stud when I was removing it.

Let's see the rims

i would definately replace that second stud. the first one might be able to be repaired though.

i agree
