[95 gst rebuild]

easy-out, screw extractor, some patience.

Make sure you spray plenty of penetrating oil on the broken bolt before you go cranking on the easy out . It don't hurt to heat it as well .

PB Blaster the broken stud several times in a day (and let it soak over night if you can, that really helps). Easy-out screw extractor (use various sizes and work your way up with normal drill bits) like mentioned above. Take it really slow, let the bits cool, and use more PB Blaster throughout the process.

I had a exhaust mani. stud break off clean in the head recently. Not fun. Just take it slow. GL

Yea man your going to deff need some patience for this one but soak like said in pb, and slowly easy out it. Take your time and goodluck.

It is it the 12mm shank bolt that holds the curved arm to the subframe than no easy out is going to get that out. You will break them all day long. You will have to weld a washer and nut to it, or drill it out and tap it.

Careful drilling and tapping If it is the bolt mentioned above. I say this because a brake line runs in-between the car and that arm. I drilled into the brake line doing mine so be careful it's a pita to get out.

easy way...drill and tap but like above mentioned take it slow and careful or you will cause more headaches.

if all else fails I have used these https://www.partsmaster.us/SitePages/products.aspx?Code=02010305 b

I think its just the heat from the welding rod that helps remove the broken bolt . These are good but they have let me down before

Basicaly you weld a nut to the broken screw and use a wrench or socket and back off the broken bolt

the best penetrating oil available is not on a shelf.

use 1/2 ATF and 1/2 laquer thinner, mix and paint onto the area( spray if possible ). this has removed so many bolts that pb blaster and any other penetrating oil hasn't that i just stopped buying the off the shelf stuff.

Get a good center punch and a reverse drill bit. Haha and some beer because its going to take a while
