subframe bolts

[akdov823]

I've been making some good progress but I hit a road block. I was removing the front sub frame and had 1 stud start spinning on me. The other 5 came out fairly easy. So what are my options on getting the last but off, obviously I could cut into the frame to access the top of the bolt but I'm hoping you guys have a better solution. Also how are these studs held from spinning? They move up and down a little so I'm assuming there is square weleded on top to keep it from spinning in the frame?

Yes there is a slot in the frame that holds the studs/bolts. Have you tried an impact gun? Cutting into the body may be your only viable option if the impact doesn't work. Other options are to cut a slot in the stud to fit a wrench or to grind the point down and drill a hole up in through the center of the bolt to hold it with an easy-out. I would try the impact and pulse the impact gun first. Any other option would require replacing that stud.

Another option is to find a spot close to the bolt that you can drill a hole and if you have a welder spot weld the bolt to the frame inside so it won't spin. Then you still have to fix the hole you drilled.

I have had the same issue on my 94. I used a 1/2 drill bit and drilled a hole next to where the bolt threaded in and put a small spot weld on the nut, It worked out great. Trust me, it is scary but it works!

Well that's pretty much what I did, I opened up a small window in the fram and expose the sleeve. Then I drilled a 1/4 hole through the sleeve and slightly into the bolt. Filled it up with weld, got the nut off and welded the window close.

Glad it worked out for you. That sucker won't spin on you ever again.
