    I've got a 72 Blazer that has 3.07 gears. I want to build this blazer just for off road use only. I have a set of axles in a 72 3/4 ton truck (D44/Eaton) that are in fair shape, but I know the front axle needs new carrier bearings. Not sure about the rear yet, but they both have 4.10s. I also have a donor 1 ton Eaton for the rear that is in great shape with 4.56s.

    My question is, can I regear the 4.10 44 to 4.56, or does it take a new carrier. I was assuming the 3.07 axle would require a new carrier, but I am new to axle swaps like this and I need help.

    I am on a budget, or else I would look for a 60, but I am also not that hardcore, just mainly want larger tires and need the gearing to run them and I have all these axles handy and own them already.

    Any help is greatly appreciated.

    i can't answer your question about the carrier, but if it were me, i'd just find another 44 to run with your eaton. i've found its cheaper/easier that way.

    I believe the carrier break is 3.73 and down, and then 3.92 and up. If I am not smoking too much crack, you should be good to go.
