Ok, so this has been discusssed some time before. I want to get my brakes changed but I can't get my back wheels off because they are dethrreading. The lugz aren't detrheaded (they could be) but the part they screw on (term please) is dethreading. And it's like this on all my wheels, there are only about four lugz holding each tire on. I heard these can be re-machined. They take off the old thread and machin a new one on the wheel assembly.
I want to get new rims and brakes but this is what stands in my way, I want to do a search and be able to talk to people locally about it, but I don't have my terms straight, as in, what is dethreading and what it's called to fix them and what not.

The part that a lug nut goes on is a stud. They are pressed into the rotor. When a new one is needed, the old stud is pressed out & a new one pressed in. No remachining is necessary.
If the nuts are jammed onto the studs, they can be broken off. The tire can then be taken off. The rotor can then be removed from the car & new studs & lug nuts put on.

They are generally called wheel studs. They are pressed in the hub, not the rotor. You can probably press them out and replace them. I've done this on the Regal but have not tried it on an Aurora.
I would not play around with that sort of thing. If the lug nuts strip off, your wheel will come off while you are driving. This is a pretty catastrophic thing to have happen.

Of course I didn't do it myself. I got it doen to all the wheels and they put sum stuff on em to make the lugz easier to come off after the initial tug. It all cost 95.00, but it was pretty extensive... I only had four lug nuts on each wheel, and only about 1 or 2 of them would be easily taken off, so a lot of them were dethreaded. I dunno which of the two owners who had this car was thinking, but if the nut aint comin off, take a look at it and see why, don't force it back on! I can also see extensive damange on the OEM jack that came with the car, which I persume proves to a further extent that he tried forcing them on...

I see you've got your problem fixed rap, but if anyone passing this thread needs to know...
First off, one of my lug studs broke off while hand tightening the nut...wonderful, I know. Anyways, you can change the lug studs on these cars without too much work. You have to pull off the wheel(obviously) and rotor. You then pound out the old stud and start the new one in. Since I didn't want to trust that it would pull tight while putting the wheel back on, I pulled the stud all the way up to it's proper position before putting the wheel back on(a socket wrench on the lug nut and being pushed up by a prybar on a different stud worked well). I then pulled the nut back off and threw the rotor and wheel on. Overall, it's not too bad of a job.

You should never treat lug nuts or the wheel stud with ANYTHING. If they put some kind of anti-sieze or lube or something on there, I would make sure to clean it off.
I have no idea what you are trying to say about them being easy to take off and relating that to being dethreaded. If a lug nut requires an overly large amount of force to remove, then either there is crud on the threads, it's rusting, or the most likely case, it has been overtorqued. Overtorquing can stretch the wheel stud and eventually cause it to fail. It also isn't very good for the wheel or the brake rotor.
If the wheel stud was dethreaded, i.e. the thread has been ripped off, the lug nut wouldn't stay on at all. Lug nuts should be put on with 100 lb-ft of torque, and it takes about that much to break them back loose again to remove. Not a small amount of effort, but hardly a lot.
Austinator, you can also reseat the wheel stud by using some thick washers and screwing a lug nut onto the stud. Once you get the lug snug, you can tighten it up and it will pull the stud straight into the seat. Another tip is to have an old lug nut that you screw on the end of the stud you want to remove. Then hit that with a hammer to drive it out, it's a lot easier to hit it square that way than trying to hit the end of the stud. The lug nut will get mashed up a little, so don't use one that you have to put back on the car.
