    Post Axle Codes

    Courtesy of member Good Samaritan. Thanks!!!

    These will/should appear on the sticker on the driver's side door. It sill be listed under "AXLE".
    For example, if the axle code says "8", then it's an open diff with 2.73s.
    If it says "K", then it's a locking diff with 3.55s.

    Axle codes
    Open/Lock/Ratio #
    -----------------------
    G / H / 2.26
    B / C / 2.47
    8 / M / 2.73
    7 / - / 3.07
    Y / Z / 3.08
    4 / D / 3.42
    F / R / 3.45
    5 / E / 3.27
    6 / W / 3.73
    2 / K / 3.55
    A / - / 3.63
    J / - / 3.85



    Enjoy.

    If that’s the tag on the axle, it sounds like a 3.27 open.
