I was changing the rear differential oil, and when i was putting the cap back on, I SNAPPED IT// the problem is, its a hollow thread, so the thread is still in there, but i cant drill it b cuz its hollow// ANY IDEAS// Thanx

 

that sucks, didnt you over tighten one when changinc your bigbear oil? any way, other than drilling it out i dont know what to tell you other than...bump

 

nooo,, only on the recon

 

Would an EZ Out work? It is a tool that is like a screw that is reverse threaded so as you twist it in, it will remove the threaded insert left in the hole. I don't know what size your plug is/was but I hope this will give you a start in the right direction. I would hope that an auto parts store will have one, or be able to guide you to one.

 

same thing happend to me there bolts are weak! i broke about 20 lol but you should be abel to tap it out if all the oil is out can you describe your problem a lil better

 

Hey darkmanx, the problem is, the cap 4 the rear differential oil, snapped inside// the cap snapped off the thread, so there is still a hole, but the thread is stuck inside there// the entire bolt is hollow and there is a cap ontop of it// I overtightened it, and the cap snapped off the thread// the hole is big enough for me to fit my finger in, but its pretty tight
Thanx

 

Two suggestions and neither one of them may work.

1) I once saw a very talented welder spot weld a large nut on top of a bolt that had twisted off in a threaded hole. Once the nut was in place he took a wrench and simply twisted the bolt out. Yeah, I know, you'll have to take it to a welder, but you might try it if there's one close by.

2) take a saber saw with metal blade. Stick it in the hole and very slowly and carefully saw through the side wall of the damaged plug. You might not have to saw so far that you damage the outer thread. If you do, you may be able to re-tap the hole. If one cut won't do it. work from the other side and see if you can remove enough material to make it calapse and fall outside the hole.

 

darkmanx- do u mean tap it into the differential fluid? theres no other way to tap it? unless i msread beezy's post.

 

BigBeezy,
I don't want to jump in here again on top of your thread, but being born in Port Jefferson, I'll take the liberty..The tool I described sounds exactly what you need. It is my understanding that you have a set of threads inside a set of threads with no way to grab the inner set. An EZ Out is your solution. It looks like I misspelled it, so here is a link to one of the sellers.

I agree, a easyout would be the solution. But might as well try something for free before you spend for the big easyout.
When the head, or flange end of a bolt, comes off, theres no longer any tension on the threads. If you get a wooden dowel..old plunger handle or broomstick, and while pressing firmly on the jagged top of the busted threads, and use it like a screwdriver ,...there should be enough friction to spin it out. If this doesnt work, try the rounded backside of a craftman, screwdriver. You may have to lightly tap the threads, in the direction to loosen, ccw, to get a stuborn one started, but most can come out with very little pressure.
Youll be surprised how easy itll come out.
