    Sounds like the pinion seal got messed up....OR...it is leaking where the spline on the pinion gear meet the splines on the yoke. A little RTV will cure the latter.

    Yes, it is a crush leaf !
    the leaf crushed the seal instead of the bearing, and now its leaking. Replace the crush leaf, and the seal,
    and do not forget the pinion bearing pre-load, very
    important !

    Good Luck

    Get the right pinion seal.
