Broken bolts

I took the cover off of the rear end and 3 of the bolts snapped. Any recommendations on how to get them out?
Oh yea, I already tried the easy outs and drilling them out. I used every bit I had and nothing. Figured I must have old and dull bits so got some new cobalt bits and they don't even put a dent in it. Iv'e never seen this when you can't even get a drill bit in them?

Any ideas?

that sucks man.

I've never been able to get out a broken bolt.....ever. I've lost track of how many broken easy-outs I've made.

Good luck man, hope you get them out.

You might try some cutting oil in the bit while drilling it. Once you get the easy out in the hole, try some heat around the housing near the busted piece. But be careful using a torch under the car.

Ok Ive done this tons of times, I'm a machinist and I see this all the time. You will need to get the a center punch and put a deep mark where you want to drill it, as close to the center of the bolt as you can get. Try to make sure that surface is not really jagged or your bit will jump around and you will end up breaking something, if it is jagged I would suggest finding an end mill or something that will make it less jagged and more flat. After that you will need to use a left hand drill bit, run your drill in reverse while drilling this, becasue it is a left hand bit, if you run it forward like a right hand bit you will not get anywhere and you will end up dulling the **** out of your bit. Drill into the bolt using cutting oil, and go down until you are comfortable with the depth, I'd say a little more than 1/2 to 2/3 of the way thru. Take the easy out and tap it into the hole you just drilled with a deadblow hammer or something similar, make sure you get it in there as staight as you can. Make sure it is in there good, you will need it to "bite" into the walls of the hole you drilled. Then take either an adjustable wrench or the wrench usually provided with a tap and die set, the one with the two knurled ends and the jaws in the center, and clamp it around the easy out and try to back it out gently, if you use too much force you will chew the easy out up and you will have to go the next size up. If it appears the are rusted in there put some PB Blaster, or whatever rust eater you prefer to use, before you go to take it out, this will help eat the rust up in there and hopefully loosen it up a bit so you can back it out a little bit easier. I hope this helps you out, and good luck getting them out, it takes time and paitence, but you will get them out!!
