    I found a D44 and a matching 12 bolt from a 77 blazer today. The guy wants 200 for the pair. Open diffs, but he doesn't know the gear ratio. How much does a D44 differ from a 10 bolt? Are they beefier? Bigger? What gives? I've never had a prob with my front and I dunno if he'll seperate the pair. Is it possible to tell the gear ratio with out pulling the cover? Like spinning the axle and comparing it to the pinion or are the ratios to close to bother?

    That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>

    Also if I buy this D44 will my steering parts match up or will I need to get new stuff?

    10's and 44's in the most part are the same, axle shafts differ by I think an 1" but other then that they are the same, as far as strenght. The steering parts are all the same.

    Anyone have any thoughts as to IDing the gear ratio without pulling the cover? I was going to mark the axle and the pinion and count revolutions that way or am I wasting my time?

    Mark your pinion position on your shaft and rotate one tire 1 time count how many time the pinion makes a full rotation. make sure the opposite tire is on the ground if open diff.

    Look for a tag on the front D44 cover at the bottom corner. There should be a tag there and it will tell you what gear ratio you have.

    Check for this tag first. If it's missing, the BEST way to tell the ratio would be to pop the cover off and look for the numbers stamped on the ring gear.
