They are like a normal nut at the bottom. But they drill out the top
so the walls are very thin and then press a steel up into them. If you
put any turning force at all too them they just mash in. Okay, well
now they look like a rounded but smaller nut. Smash a new socket onto
them. Turn it and they round over again. I just got a pair of
vice-grip "nut out" (inverse of a screw/bolt out). After this fails
(as I am expecting) what would you try? I am thinking two things:
A) Weld a lug nut onto the remains of the current ones.
B) Weld a cheap socket inside of the remains of the current one.
B while more expensive sounds a little more full proof. I can really
get a good strong bead on the socket and not affect the drive hole.
BTW it is a 1985 K5 with I (believe) stock aluminum rims. I have the
"wheel cover" off so I could get "that much" closer to the rim.
Had too. Forgot to mention the previous owner purchased the wrong kind of
nut, and if you don't tighten the piss out of them the wheel can work them
loose and your wheel almost falls off doing 70MPH (ask me how I know that
one!) They are flange and it looks like I need a shallow mag... the stud is
narrower than the hole so if you just hand tighten them.....
I'm thinking of that as a last resort. I don't mind damaging the studs in
any way shape or form (already started drilling one out but decided I wanted
this done before I was dead). I think it might damage the wheel/rotor. I'd
like not to damage the wheel, though I already have one damaged and probably
should get new rims... can anyone say "steelies?"
I'm not a mechanic, so take this for what it's worth. I saw a real mechanic
round of the lugs on a car he was working on once. He used what looked like
an impact chisel (if there is such a thing - it was some kind of air tool)
and split 'em right down the side.
You might try that...
You could try force-fitting a steel plumbing pipe over the nut (I.D. of pipe
a fraction smaller than O.D. of nut, use a dead-blow or copper hammer), then
use whatever tool is available to turn the pipe. It may help to heat the
pipe-over-the-nut with a propane torch before you attempt to turn it.
