    I just pulled the cover on a Dana 44 front in an '80 Chevy. Stamped on the ring gear is the date 1977 and 50-11, which divides out to 4.545.

    I went to rotate the pinion, and clunk. The pinion gear barely even touches the ring gear. Nothing's chewed up or broken, they just dont mesh.

    I'm thinking someone stuck a 4.55 Dana 44 ring gear on a 4.10 carrier. Does that sound like a feasible explanation?

    Carrier break for D44 is 3.90 and up. Unless they put it on a 3.73 and down carrier???????

    Could be. I took another look. The pinion barely touches the ring gear.

    I pulled the cover off the rear. 14 bolt FF, 1978, 9-41. So, 41 divided by 9 is 4.5555. I was expecting to find a 3.73 rear or something.

    I wonder what's messed up with the front gears to make them not even touch. I wonder if the pinion is even for a 4.56 ratio.

    Then you'd have a 4.32 understroker. /forums/images/graemlins/tongue.gif

    If you can look in there and see the end of the pinion gear, sometimes the tooth count is stamped there as well.
