    Default possible axle swap question

    ok a friend of mine has a complete set of chevy 3/4 ton axles he wants gone said i could have them if i hauled them off..

    my question is this. i have a 77 cj5 with 304 v8
    how hard would it be to try and swap those axles with my stock (witch has a SOA) ?

    and is it beneficial at all to do this?

    this jeep is strictly a toy not a DD

    a few factors..
    how wide are the 3/4 axles compared to your current axles?
    do the front axles have the diff on the same side?

    the axles are i think 9'' wider if i remember my measurement right and the diffs are in the same locations.

    Is it beneficial, yes. Especially if it's a toy. The rear should be a 14 bolt, and the front a Dana 44 (at least). I think it would be a great upgrade. Plus the Chevy fronts are already setup as SOA. You will need to outboard your springs, but that shouldn't be a problem. There are lots of info on the web, w/pics.
    The 14 bolt rears are easy to work on/setup with different gears & lockers. Most came with limited slip, (I would chuck the LS for a locker). Keep us updated, and take lots of pics.
    Later, T.J.

    Out board your springs
    What do you mean by this? I am thinking of doing the same thing with this type of axle upgrade just trying to do my research.

    "outboard the springs " refers to moving the springs further out on the frame (or even to the outside of the frame) depending on how wide the spring seats on the "new" axle's are to get all the ride angles to match up.

    sounds easy but there's allot to it. as far as the swap goes outboarding the spring perches will be out of my knowledge area as far as have never done it. only read a few snippets in other posts and will be the cause of me putting it on hold till i can figure out how to measure and such to make sure i get the correct angles.

    You can buy a kit to put full-widths under a CJ. Check at www.mountainoffroad.com. They have a complete kit that will outboard your springs. They also have the things you will need to correct your steering. You can use the pics on theit website and make your own brackets if you are handy with a sawzall (or plasma torch) and a welder.
