Stripped on of the 12 point bolts changing out my CV axles. Broke off an extractor inside of bolt. What are my options? Im so pissed, these things are usually a breeze.

take a 13MM socket- or one that fits- and pound it over the outside of the bolt. Then unbolt it.

I think some people replace these with Allen heads (SHCS). I think I will look into this next time I am working on them.

Im going to try to pound on the 13mm. I tried a 12 right befor I read these replies, its too small. Thanks.

Get the craftsman stripped screw removal tool kit. Comes with several sizes. Worked like a champ when I had a stripped flywheel bolt (same bolt as the CV joints I believe).

What's wrong with Vise Grips?

Matt O.

I take it you've never pulled the CV joint? There's no way to get vice grips on those bolts.

Serviced all 4 of mine, and I couldn't see why Visegrips applied on the side of the head would work it right out.

If you snapped the head off and left part of the stud in, then they're pointless.

I second the craftsman bolt-out kit. Comes in impact grade and standard grade. It completely saved me when I stripped out the long turbo mounting bolt.

Lorax

I got it out! I was lucky this time... I got the little blade on my dremel and cut the little metal gasket right out from underneath it, and i was able to get it on the second try with the 12 mm hammered on.
PS - vicegrips were next to useless, though maybe im just not good enough to use them well in that little space.

Now I know why- I have someone take it in and out of gear as I rotate the wheel. Then I lower the car back onto a ramp and remove a few more bolts on the bottom of the assembly. I couldn't use them up above the axle.

Lorax

Thanks for the advice, guys.
Looks like im almost done after 3 stripped bolts and one new triplesquare driver. One hour job my ***. (isnt that alwasy the way it is?)

Did you pound a 12 or 6 point socket over the bolt. And were they on the transaxel side or the wheel side of the axel? I am going to tackle this tomorrow afternoon. I originally slotted the bolt with a dremel in order to get it out with a LARGE flathead screw driver. But, broke the tip off of the screwdriver

I was able to use vicegrips when I ran into this.

I've used vice grips lots of times.
