    Where or how do I find out if I have 28 or 31 spline axles on the rear ?
    I have a 02 ranger 4x4 w/4.0 auto and 4:10 gears.

    There should be a tag on the rear diff or and I am not too sure of this, the numbers on the door post, some how that can be translated.
    Good Chance it is a 28 spline unit.
    Ranger FX4 LvL II’s had the 31 spline and the Explorers do along with the LS.

    I found a tag on the rear diff cover, mine had a few letters and numbers, don’t remember what.
