I have a '79 F250 Pick-up with a Dana 61 rear axle, 8 lug wheels. I am in need of info/procedure to remove rear brake drums for inspection. I know I need to remove the axle flange screws and pull axle out. What size socket is needed to remove bearing nut, and who makes the socket, source, MAC, Snap-On, etc.? Is a special thin wall socket required? Also, what comes out of the bearing area next? Any shims? Any other precautions I should be aware of? Any torque values on nut, or just adjust nut tightness to give a snug feel on wheel bearings similar to a front wheel bearing? Thanks for any advice, suggestions. John
