    Default Auto locking hub help

    1989 GMC Suburban 1/2 ton 4x4 350

    The left front hub is giving me problems unlocking/disengaging. I took it apart and cleaned/greased it and it's still doing the same thing.Very aggravating.

    Can somebody give me some advice on fixing this?? I know I can replace them with manual hubs, but don't have the money right now. I also can not find a schematic or diagram/exploded view of the asswmbly itself. HELP!?
