So I didn't realize that I had to extract the steering knuckle to replace the lower ball joint... I already disconnected the tie rod end, removed the caliper and rotor, removed the upper ball joint, freed the lower(but it won't come out until the axle is out of the way. I have removed the 36mm hub nut, and the three 18mm back nuts, but the whole thing is free-floating. Is this all I have to do to remove the hub assy? Should I just put a big gear puller on and push on the spindle while pulling on the hub?
