I am tearing apart my wire wheel front suspension for an inspection and rebuild. After removing the wheel it appears that the dust cap is recessed in the hub with a 5/16 stud sticking out. How do you get the dust cover off and remove the hub? Also when trying to separate the A arm from the spindle I can't get the tapered pin out. I tried driving it out with a brass rod and hammer. And, the plug that goes over the fulcrum pin (it appears to be aluminum) is frozen. HELP
