Mcgard wheel lug nut cracked in half.

Mcgard wheel lug nut cracked in half. Anyone have any ideas how I would take the remaining piece out without drilling the stud?

Lift up the car and use and angle grinder to grind off the stud from the back side of the hub.
Remove the rest of the lug nuts and pound the broken stud through.

Are you sure the back of the stud is easily accessible just by just raising the car? This is one of the rear wheels on an AWD. If I remember right from the time I changed one of the rear hub assemblies you’d have to take the rotor off to get to the back of it.

Yes, most likely all the parking brake junk will be in the way.

I think grinding the stud from the back may be your only option....despite the crap you may have to go through to get to it.

Vise grips, pliers?

Tried that. The problem is that if you look at the pictures most of the "meat" to grab onto was left inside the wheel.

I had the same thing happen with one of my aftermarket lug nuts when I had motegi mr7 rims on my car. It was a 95 GSX but it happened in the front. Didn't have the time or space to deal with it. I brought it to a shop and they replaced the stud for $50.

You dont have to take the rotor off, just slide your grinder in behind the backing plate. If your backing plates are in good condition and you have an air compressor or a high speed drill you can drill a 1" hole in the backing plate and use a die grinder to grind off the head of the stud.
If you don't want to mess with doing it that way than your only other alternative is to drill it out. Start small and work your way up. Just more of a probability to damage your rim with bits braking or sliding around.
There are special sockets for removing lugnuts, stripped bolts, and broken lugs, but in your situation what your left to work with leaves you only a few options.

Grind or drill.

PB Blaster, and what's left may have enough area to take a few slugs with a drift and unscrew. Or, if you're lucky, it might break enough off to let you remove the wheel where you could get a set of Vise-Grips on the remaining threads.

Drilling will probably be your only option. And for what it's worth, if someone uses an impact gun on them they eventually break like that. Loosen and tighten that style lugnut by hand. Check the rest of them and replace if they have had an impact gun on them.

 

[tommiman]

I'll try to do the drift method as Defiant mentioned. If that doesn't work I'll drill it out.

As far as the other Mcgards go I'm just going to replace them with regular lugs since there are sockets that can remove them.
