Long story short, i went up town one day. I was leaking oil, and found a snapped bolt down there, along with a few kind of loose bolts. I naturally continued to tighten them all up. alls good but then one more snapped off. Leaked more.
Ended up JB welding a little to slow the leak and got home.
Now i attempt to extract the bolts with my dad.
one is towards the back, about under the crossmember that holds the T Case. ones off to the drivers side. Drivers side one we can get to easier. Drill a bit. Try left handed bits, try some ryobi bolt extractor. Ryobi thing breaks off in the bolt.
To say the least, I'm mad.
SO, options i see. Drill to the side of bolt weve been working on, retap it and get a bigger bolt. BUT the other bolt we cant get to too easily.
can i make a steel plate thing with an angle, and holes in it for bolts, and attach that on there to spread pressure? See attachments. Thanks

Really gotta figure something our soon. Or worst case can I use some kind of sealer on it? Jbweld or others?

dont use jb. you should be able to get away with using "the right stuff" its about $15 at the parts store but we use it on axle covers and timing plates valve covers. i would drop the pan clean up the gasket surfaces put the stuff on like the directions say. then put it back on without a gasket and refill and go. it will be a pain next time you change the fluid but wont be too hard. also you might have to unbolt the rear transmission cross member and slide it out of the way
-
For the rear, I would put a jack under the transfer case to hold it up, and remove the crossmember.
If you've got a welder, you can tack weld a new slightly smaller bolt to the broken one, and use that to twist it out.

What would that be? Just rtv?

So do those bolts on the crossmember just come out, and then remove the member?
and i do have a welder, its stick. Not the easiest for small stuff

If i recall correctly, there are two bolts for that transmission mounts to the crossmember, and four for the crossmember to the frame, remove those and it should come off. (good time to check the mounts and replace if nessecary)
If the bolts aren't stuck in the holes too bad (like they broke because of over-tighening instead of rusting in place) then just weld a heavy stick to the bolt and use the stick itself to twist them out. Also soak em in some WD40 or PBblaster for a day before trying to twist em out

Use that instead of a gasket. Or in addition?

instead
