    Did you get the entire pinion shaft lock screw out, or only the threaded portion right below the head?

    If you got all of it out, it may very well be the pinion shaft itself is all torn up, there was another post about this same issue no more than a week or two ago.

    Well, the pinion gears will sometimes wear out the bushings they sit on, wobble on the pinion shaft, and gouge the sides of the pinion shaft where they ride...those edges will then catch when you try and pull the pinion shaft.

    Sounds to me like you haven't got the entire pinion shaft lock screw out though. The screw is threaded only at the head, the rest of the screw passes all the way through the pinion shaft, and partially into the carrier on the other side. Hold what you've got up against the carrier to see if it is that long. The end of that lock screw, on all that I have seen, is rounded.

    Try and tap it out. If you tood out the bolt you should be able to tap it out.
