Major Axle problem!! Need help

[Wheels-a-turnin]

Ok so I'm an Idiot, I built an engine and noticed that the place where you screw the driverside axle into place on the block was stripped out. Well I ####ing forgot to fix it before i dropped the engine in. I need some ideas of how to fix this without pulling the engine. Its extremely difficult to try and retap it, cant get drill down there.

I'm sure you're not the first person to have done this.
Did you try a search?
If you can't get a drill down there to helicoil it, you will have to pull the motor.
Do not band-aid this, you will be sorry.
Those 2 screws hold the carrier bearing for the driver side front axle.

Maybe you can try to remove the lower front to back cross member, you know the one that has the front roll stop motor mount.
Remove the timing belt side motor mount, and lower the motor with a jack and a piece of wood and try to get a drill in there so you can helicoil it.

Even if you retap it, you will still need to redrill the holes in the carrier itself to accept the larger screws.
Hopefully you can helicoil it and be done with it.

This is fun.
I used a chuck from a hand drill that had a sliding bar through the top. Lots of WD40 and I just turned the tap by hand at first and then with a wrench over the sliding bar. Keep in mind, the whole assembly is only about 3" long so it fits but it's really unwieldy. Tap the bracket with the same pitch/diameter and bolt it up. I suggest only going up in size as far as neccessary on the tap so you don't have to chew a bunch of metal.
Hope this helps.
