Taking an air chisel to a lug nut

My Nova has a couple of those locking lug nuts on the rear wheels; the kind that take a special socket (key) to turn. Well, nobody has a key that will fit it and I'm considering taking my air chisel to it to just break it off.

Does this plan have the potential to damage anything behind the wheel (drum, axle, etc)? Not counting the obvious danger to the stud, of course.

Obviouslly, you don't care about the wheel. If it were me, I would cut it off with a torch....carefully.............It will wreck the stud, but that is easilly replaced.

If a plasma cutter were available, that would be the way to go.

air chisel

I work in a tire shop and weve had to air chisel a couple off and it didnt hurt anything. but you do have to replace the stud of course. Or if you can get on a mac tools or matco catolog and they sell sockets for taking off wheel locks. Hope this helps.

Thank you both for the great info!

Unfortunately I don't have access to any kind of torch

Checked Mac and Matco. Mac's online catalog is under construction at the moment, but I found a few sets at Matco. Prices range from $75 up to $167. I don't mind paying high prices for good tools as long as I know I'll get lots of use out of them. This set, however, I would only use this one time and I can't justify those prices with that. Looks like I'm going to go with the air chisel and hope I don't do too much damage.

One more thing. Did these wheel locks come stock from GM? The wheel is a Cragar S/S (obviously not stock) but the sets listed at Matco mention GM wheel locks. If they did come stock, maybe I can get a key from a dealer?

I'll see what I can dig up. Thanks again for the help.

If you want to try and save the wheel.I have had better luck with just a big hammer and chisel ,the air hammer bounces around and gets to the wheel.You could also try an old socket that you don,t mind destroying and hammering it on the lock.Carl

I have used stuff like this http://www.sears.com/sr/javasr/produ...id=00904458000 but they only will go up to 3/4" so you might have to use a grinder to do a little work on the locking lug before you can get it small enough to grab.

There are lots of ways to remove it, but since you dont have torch, welder ect, it limits you. If you are going to beat it with a chisel, I would cut a piece of wood and drill a hole in it to protect the wheel WHEN it slips off that one time.

Have you tried vise grips and hitting them with a hammer?

I do them all the time as well... I use my good Snap-on air hammer with a chisel that I have shaped from a blunt type... I made a wedge like a reg chisel on the end which is kinda narrow... It will bite into the lug nut (try to make a V indention into a good area) and using a pair of gloves just start it going counter clockwise till loose enough to remove... Just be careful and use the trigger to the air hammer with care too... Or else you`ll ding the crap out of it... Never failed me yet (Even on a Dodge truck wheel...)

This particular lock is completely round and smooth on the outside diameter of the nut. There's no way I'm going to get any socket on tight enough to loosen it. I have tried vice grips, but given the restricted space around the nut and its smooth outer surface, they had no chance.

I'm going to try Bumpstick's strategy in the morning and see where I get. Again, thank you all for the great tips.

Can you get an angle grinder and grind some flats on it then try the vice grips? Maybe some heat from a propane torch?

air chisel

I totally forgot about this in my last post. If you wornt the last one to deal with teh wheels its the shops fault for not torquing it to specs. Just take it to them and let them deal with it and they should also replace the stud for free since it was thier fault.

Bumpstick is right on the money on how to get the lug nut off. If done properly you wont have to replace the wheel stud, just the lug nut. I have taken many off this way. Good luck.

Use a 1/2" drive deepwell impact socket that won't quite fit over the round nut, using a BFH pound it on to the nut and wrench it off. This is the most used method by your local wheel thief, fast easy and cheap and dosen't hurt the wheel. The nut is fairly soft steel, softer than the socket and will deform to the interior of the socket turning it into a sort of hex nut.
