    Most OEM stuff is rolled, and I know Superior axles are rolled. Most of the aftermarket is cut since there is way less equipment involved to do it.
    There are many different spline pressure angles, common GM stuff is 45 degrees, lots of Dana parts are 30 degrees and I'm sure there are more variations than that.
    The only spline operations I've been in on have been single point using a tool the shape of the tooth, and one using a rotary table on a mill with a cutter to match the spline angle.
    I know some of the bigger axle companies use some pretty specialized tooling to run splines, one in particular doesn't even let anyone in the room with the machine!
    Hope this helps, I know it's not much info, but there's a lot to it.

    Stephen, any idea where I could find information on how to cut the internal splines (angles, critical dim's, etc) on 35 spline stub? I'm considering modifying my OE Spicer hubs for 35 spline but need to be get a drawing of the splines.
