Hi BIG D, straight forward, pull axle out, undo nuts that retain wheel bearings, remove drum. You will see the inner hub seal, get a new one from AJ'S $50 each or I can send one down. These are held in by a retaining ring, that can be tricky to flick out, use small flat blade screw driver to lever one end of the retaining ring out, you will see there is a slice cut on the ring for such a purpose.
Knock the inner bearing out and the seal will come with it probably, should take you at least 5 mins for the job, cheers Andrew.
