i was installing my 4.10s and the cross pin bolt got stripped and now im stuck. anyone know what i should do from here?

 

Stripped the hex of the bolt?
Stripped the head off the threaded part of the bolt?
Stripped the threaded bolt off the smooth pin?

If it's still partially threaded into the diff and has no hex head, start w/ a small left hand drill bit at the centre of the remaining bolt.

 

I stripped the head of the bolt that hold the pin in that hilds the c clips

 

See if you can turn the remnant out with a scriber or pick. Usually they break off at the last thread so there's not too much holding it in.

 

Wht do you mean?

 

Are you saying you rounded the head of the bolt or you broke the head off the bolt?

 

the head is rounded. its a 5/16 bolt and is in a tight spot

 

Hmm, Never had that happen on a pin bolt. I'm guessing you used a 6 point socket, If it was me I would try tapping the next size smaller metric socket on the head, if that doesn't work I would drill a hole in the head and use a easy out. Sorry I couldnt be more help. Maybe someone else will chime in who have ran into that. Good luck.

Mark.

 

There's a tool especially designed to extract these. Got mine from skyway tools: Differential Repair Kit ST 1440

 

My guess is that he didn't use a 6-point--at least I've always used one to good effect; it's the 12-point that usually causes issues. At any rate, tool in post #17 of the link below:

Its all good thanks man

 

i second this.also sears craftsman makes special sockets that will grab rounded bolt heads.

 

Ok ill give that a try thanks

 

hammer and a small chisel works for me

 

You can also use a lil valve grinding compound on all the sides of the bolt flats for more grip. If your trying to get it out you can use heat to loosen the thread locker 1st. That makes it easier to remove..

 

The bolt is so seatroyed now ive tried so mny things im gonna try to drill it out
