Yes, and if there was to be pitting, that is the least stressed section IMO.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I'm not convinced that that area was bright and shiny on the spindle when new. I suspect it's an area where the forging was only big enough for the machining to take off the top of the bumps, leaving the bottom of the bumps as-forged. In service that area is usually covered with grease.
R. Hmmm....never thought of that. I was wondering how it could have gotten rusty in the first place, since it should been covered in grease.

Nope. I know the stresses are not great in that area, but that pitting is a great source for stress risers. Significantly increases the chances of cracking and breaking. I personally would not risk it.

I personally would not risk it. That's exactly what I was wondering about when I posted this. Grind them out then. Sorry, but we are starting down a path that could very well make this worse for the OP. It appeared to me, and not if addressed already, seems like the spindle has already had some mechanical surface de rust prep in posted pic. That was smart, and only improved matters. Going further with grind marks, causing minor localized heating, and/or grind marks orientation, etc, are a risk, and not worth it. Additionally any metal removal is hard to see as a plus. If there was one or two serious depressions, which I don't see, there would be the issue of concentrated stress riser. The fact that there are numerous rust cavities, actually spreads the stress out over a larger surface area, minimizing any single large stress concentration. As also already mentioned, I always coat the area shown pitted with grease, for this very reason, due, to exposure some how, by immersion, or condensation.

Granted the stresses are much higher, but in my career I have seen many rotating shafts break because of stress rises caused by that kind of corrosion. Each one of those pits has stress risers.

Yes, I agree, but I believe I have taken that into account correctly in my thinking. On a related note, ever seen a fully "knurled" (literally hundreds of stress risers) rear axle shaft, and know why?
