Unfortunately my percieved leaky rear wheel cylinder has morphed into a leaking rear axle seal replacement instead. After reading on here all about the axle thrust spacer/pin/shim/locking C-clip info, AND looking in the FSM, I'm still curious about how these axle C-clips actually stay in the axle groove. Don't they just slide on & off? And should they always be replaced? Or just if well-worn?
The C-clips stay on the axle groove because the spacer block won't allow the axle to move far enough inward. They are retained in the side gears. Once you remove the pinion shaft and the spacer block just push the axle inward, it helps to have someone else do this while you hold a magnet near the end to catch the C-clips. That assumes the easy version, sometimes they don't fall off and you have to work at it. IIRC, axle end play is adjusted by the thickness of the spacer block and various sizes are available.
There is a recess in the spider gear which prevents the C-clip from coming off the end of the axle. There is a metal block between the two axles which keeps them in the recess. Remove the block, push the axles inwards and the C-clip can come out.
They don't usually need to be replaced as wear on them is minimal.

Got the axle out. Took a prior measurement of the clearance between the spacer "block" and each end of both axles. Got a .08mm, and the other side was .1mm- in tolerance thankfully. Took a good look at the R&P gears and the spider gears, and all had a good pattern, again thankfully! Before removing it, I noticed the offending (leaky) seal didn't appear to be perfectly square in the bore. Tomorrow it's assembly time!
