I like working on rear drums. I will admit it took me about 4 hours my first time. Believe it or not it was on a Limo about 12 years ago. The more you do the easier they get. Just remember keep the other side together, it is a mirror image, everything is backwards. Also the shoe with the most friction material goes to the rear of
the truck. Always check your emergency brake cables, if one hangs up on you it will toast your brakes. If you have access to a compressor, an orbital disc sander with about a 5 in disc, use it to get rid of that rust ring near the outside of the inside of your drum. (Here in Ohio we have rust everywhere, you might not). This will
help you slide your drum on when your done, and make it easier to adjust up. When adjusting I adjust till there is very very light drag. The only tools I would recommend to make your life easier would be a hold down tool (screw driver handle with round opening at end), and a spring tool (almost shaped like an s). Hope this helps.
