Leonard, it's not realy too bad of a job to get the front off. On the hanger, there's a wedge bolt that locks the pin in place. IIRC, the nut is on the front side of the hanger, once the nut is removed, you should be able to drive the wedge out through the back side. Then the pin is driven out from the side. You shoulc remove the grease fitting first to preven damage/allow clearance. The wedge bolts are readily available if you should damage one.
