Hi g2gsoon.
This parts book image should help.

The brake caliper would need to be unbolted from the stub axle and tied out of the way so as not to strain brake hose. Straightforward disassembly after removing hub nut to allow hubs to be slid off and so gain access to remove disc nuts and bolts from same. After cleaning all parts re-fitting discs and re-greasing bearings, re-assemble with castellated hub nut adjusted to put no pre-load on bearings and no play either before inserting split pin.
