I am trying to do a brake job on a 2005 Ford F350 dually w/ four wheel drive. I am trying to fgure out how to remove the front brake rotors. I removed the caliper and bracket, the locking hub assembly, and I found four studs coming through the back side of the steering knuckle. I removed the four nuts and beat around a little, but so far nothing has come loose. I see a snap ring that holds the axle shaft into the end of the hub, but I have not removed that yet. Can anybody tell me if I'm opn the right track, or am I missing something? Thanks if you can help.
