SA makes those special washers. They are serrated where they meet the frame so the axle won't slide, they have slots instead of holes and shoulders to keep the axle from turning in the frame. Most of the SA axles are flat so they lock to the special washers that lock to the frame. Using just plain round washers won't hold the axle in place and keep it from turning. With any hub that has a sun gear, the axle will want to rotate backwards when you pedal forwards. The sun gear is the anchor for forward torque.
Alloy shell? Those crack, break apart and cause all kinds of trouble.
Also, check the frame for breaks. I've seen bikes where the brass brazing on a chain stay let loose allowing the stay to slide in to the bb shell. If you ever watch the movies at the Raleigh factory, the brass brazing method is a far cry from having a frame custom built. They nail the frames together with a small ring of brass inside, set it in front of a torch for a while and call it good. There is really very little brass holding the lugs in place. A couple years ago, I got a Raleigh where they didn't braze the seat stays to the rear dropouts. Oopsie. Held together with paint at that joint that is normally under compression.

Subject: [External] [Gentleman Cyclist] S5 Hub Trouble
I recently started having trouble with my S5 hub this fall. It has worked well for the past few years, but it started to feel "draggy," and occasionally it seemed to stick, which could cause it to move in the chainstays or the sometimes the chain would pop off. I took everything apart, except the axle/sun pinions assembly, regreased/oiled, and reassembled. The clutch was chipped so I replaced it. It seemed fine for a few weeks, then started having trouble again. It was working one day, but the next morning was jammed--I couldn't even roll the bike backwards!
I gave up and hung it up for the winter, but any advice on rebuilding? I suppose I need to disassemble the axle/sun pinions, but any idea what the problem could be?

A common mistake I see is people reassemble AW hubs and adjust the bearings to the left side first. That can shift the entire axle to the left and that takes the sun gear with it which can cause all kinds of trouble. It's not at all obvious as the bits are hidden inside, out of sight. Reading SA's assembly instructions can help get it right.
