Need help drilling out a broken subframe bolt
Hey guys,
As you may have seen, I snapped a 19mm sub-frame bolt when I was doing my clutch install. I highly suspect the threads are galled.
About 3-4 inches of the bolt are still let in the frame.
Are there any shops that you would recommend that can drill it out using a guide/ jig so they can drill as close to perfectly in the center as possible and then clean the threads with a tap?
mines13 maybe
I REALLY want to avoid having to cut the frame.
Thanks in advance.
James

You can drill it out and rethread the hole. I never done it but i hear its not that hard.
I'd much rather pay a shop to do it since they can get the car up on a lift.
Also i just don't trust myself to drill it perfectly centered.

is there enough of the bolt sticking out to get a welder in there and weld another bolt on, heat it up with a torch and remove the old bolt?

How would you drill it so it could be as close to center and as straight as possible? \
This is not something would let anyone do free hand.
I have absolutely NO experience with this kind of stuff. Also, do you have the tap needed to re-thread it?

A bolt puller might get the rest of what's in there out...so you wouldn't have to worry about it being the absolute straightest hole...and then just retap the hole.
I have a tap set if you guys decide to do this at home.
