    i have had a 14 bolt sitting in my yard for a while and i am close to installing it. i felt lucky that the spring pads were correct width but i was under the impression that it had a 4:10 or 4:56 ratio. i open the diff and check the numbers on the ring and the last few are 14 45 10 86. does that mean it's a 3:21 made in oct. 86? i never heard of 3:21. what options do i have to regear? is there a carrier break? what do i do? :confused:

    If your numbers are correct your math is right. The carrier break is 4.10 and down and 4.56 and up. So if you do have 2.32 or what ever you can go as high as you want because they sell "thick" gear sets in 4.56 and up so they will fit on the 4.10 and down carriers.

    can i just swap in a new 14 bolt carrier with 4:10's or 4:56's and be done with it? i think the answer is yes but i just want clarity. my jimmy is diesel with a 700r4 and i am running 35's. so i think i would be comfortable with either. thanks.

    which is better for strength- thick gears on a small carrier, or the thicker carrier for 4.56 and numerically up? I'm trying to decide what to do myself. Can the front Dana 44/10 bolt also add "thick" gears in, say, 4.56 so you don't have to change the carrier up front as well?

    the easiset way to tell what ratio you have is to mark a line at 12 on your brake drum or whatever you have left on the axle, turn it two full revoltuions back to 12 and watch how many time the driveshaft yoke spins fully around. It should spin 3 1/4 turns if you have 3.21's

    You would also have to change the pinion of course. But there is no reason to get a new carrier yours will fit any gear ratio. Find a used set of gears cheap and swap them out. No matter what you do you will have to "set them up". I think I might not have answered your question.

    Not sure about a front 10 bolt, but I know for sure the no thick gears are available for the D44, must repl. carrier, but they are on 45 to 50 bucks, not to bad.

    No thick gears for a d44? ever heard of a jeep rubicon? they have 4.10 gears stock that fit on a older d44 3.73 carrier. I know this for a fact cause i have them front and rear in my scout.

    What are the chances of pulling the whole R&P, carrier, and the pinion 'housing' and sliding it into another axle and having it all work right?

    Is there enough adjustability built in to tweak it without doing the whole nine yards?

    I got 2 14BFF axles with 3:73's, if you're interested, email me at steve_kelly1@yahoo.com. My wife would love to see them gone (cheap).

    Thanks, but I to am the proud owner of a pair of 3.73 geared 14FF's.

    I think I found 4.56's though :D .
