    You've read the title and that's the lowdown.

    It's one of the bolts on the carrier bearing caps on a D44. Fawking thing rounded off when I was trying to pull the gears.

    Is the best way just take a size smaller socket, apply BFH to said socket and beat it onto the bolt?

    Have you tried to drill it out with a smaller bit than the bolt hole and then use an ez out?

    Actually, I'd try the next smallest metric socket (smaller increment) for the best of choice. I ain't no rocket scientist, that's my wifes job. The only other thing I might add would be patience. Good luck to y'all.

    You can get some for cheap at your local auto parts store. I have used all kinds of them. I like the square ones best. They seem to get the most bite on the remaining metal.

    heat it, then try the small socket

    If that don't do it a pipe wrench/monkey wrench works good if you can get to the head

    If your good enough to tig a bolt to it thats a solution as well (without overheating obviously)

    Wow
    That's a pertty important bolt
    first up its a 6 point bolt head right ??
    1st use a Good name brand Snap on , craftsman 6 point Scocket not a 12 point p.o.s.
    2nd then like Allan said use the next smaller metric scocket
    then like you said tap it on there real good make sure its all the way on
    then if at all posible use a impact gun not a rachet
    finally good luck

    If you want to try a cheap fix without buying the ez out, get a torx bit just a little bigger than the hole you're drilling, but it has to be the kind that goes on a ratchet, and tap it in with a hammer. Put on the ratchet and back it out. Just try to go as big as you can, cause they can break easily. It's gotten me out of a bind before. They're pretty cheap. Just use it as the last line of defense. Try the socket first.

    cheap 12 point socket of the next smaller size, standard or metric, hammer it on, if you cant get it hammered on, use a cut off wheel and lightly split ONE side of the socket, then hammer it on and take that sucker out.. ive used this for removing the round edge wheel locks...

    These work absolutely bitchin. They have saved my ass many times at work. you hammer them on and as you loosen the bolt or nut the socket tightens itself onto the bolt. I dont know if craftsman has anything similar.

    they work very, very well. my Snap On set saves my butt consistently on the corroded marine stuff i play with...

    wish they had them suckers 20 yrs ago.. a very worthwhile investment...

    Try welding a elcheapo socket to it. The heat will help loosen it up too.

    I was always lucky to have a mig welder around ..I have used a piece of steel to weld to the stud or stripped bolt, then while it was still hot, turned it to loosen it ,the broke the the metal bar of the bolt . Some tines I drilled a hole in a piece flat bar so I could weld it to the bolt and not to the part that I was saving .
    If you are going to use extractors ,use only the square kind not the screw kind and with the square kind, tap it in just enought so they bite . DONT BREAK IT OFF IN THERE !!!! /forums/images/graemlins/deal.gif

    I have welded an old 1/2 inch extension on w/ mig and then cranked it off with a large 1/2 inch impact wrench. Works like a charm, just be careful not to weld the bolt to the carrier !
