Those are not axles or anything broken that is going to cost you anything, need to buy an entire vale or going for broke. They are brine flow stops and they need to be simply replaced in their holes near the edge of the level when reassembling the lowest level. New models use small balls. I actually like to posts better than the balls. The 'gears' are more like splines.

It is all quite easy to do; let me know if you need proper advice.
