    Will help probably, but in most cases the bolt is already broken before you even touch it (from beatings taken from the pinion shaft).

    Being that this seems to be the most common bolt that breaks (on me too), I would say so...

    The scribe method just worked for me. The broken pin still had one thread remaining so I was able to spin it right out. Total time for job about two minutes.
    The pin holding the side gears had to be driven out too, it is badly scored. This rear was badly abused before it became my property.
    Thank you to everyone that contributed to this thread. Your advice solved my problem.

    Usually there is one thread or half thread left. My Snap on kit consists of a long reverse drill bit and a bolt with a hole bored in it. I've only used it once and it worked. But all the others I've done, I've done with a pick, and I've done many. I use the kit as a last resort. Sometimes you have to move the pin a little to take any pressure off the bolt. And yes, the bolt is broke long before you touch a wrench to it.
