Whats the best way to do this? I have tried vice grips and no luck. I have tried to notch the head and use a flat head screw driver / drill and no luck Whats next?
You can always drill it out....but then you'll have to re-tap the hole if your going to be re-installing a bolt.
If you use an easy out be very careful if you break it off in the bolt you are screwed. Soak the bolt with PB Blaster first
if you break an easy out in there you will be screwed though. if it doesnt come right out, take it to a machine shop.
if you have enough room, i've always had a lot of good outcomes with just screw extractors. drill a holl in the sheared bolt, stick one of those bad boys in and it digs in and pulls out the bolt.
soak, re-soak, then soak again in PB blaster let sit for an hour or so then repeat, then try to get her out.
Well luckly the bolt is not for the subaru. Its on a diff cover for a rear axle i am about to put in my jeep. I dont feel like lugging the 300lb axle around to shop if I cant prevent it.
Heat that sucker up and see if you can vice grip it out. They also make a socket that's a twisty style easy out that you can get too.
depending on the mechanism on how the bolt is stuck, this can make it worse. it also causes the bolt to expand making the threads tighter and galling (plastic deformation) can occur
That is true Nicad. Which is why I bought a cheap $100 welder. Find old crappy bolt, weld sucker on, twist off.
On my 96 civic I broke off a lower shock mount bolt. They are known for seizing even under the best conditions, and these had seen a couple of salty winters. I torched it, let it cool, drilled a hole in it, and used an EZ-Out jury-rigged to the end of an impact wrench. I thought i was breaking the car as it popped loose, but it worked!
Yeah, that's what I was thinking, but I have broken extractors on that same bolt on other cars by using too large a breaker bar. The one that survived the impact has been placed in the "tools hall of fame" in the shop :bowdown:
