Looking at the two cups, one can clearly see the notching. The upper bearing, carrying the brunt of the load, is much worse.
This is, in fact, actually very common when bearings are used in this type of application.A shaft that is carried by bearings but does not rotate constantly and is subjected to vibration and shock loading tends to have this effect on it's bearings. I see it often in Tractors and other heavy machinery. Poor preload adjustment will of course accelerate such problems.
Lately, manufacturers are trying to overcome this by running Teflon coated convex and concave surfaces directly against each other without bearings.
Anyway, other than packing the bearings properly when fitting and ensuring proper preload, there's not much you can do.
It's simple and quick enough to replace them.
Just don't try to remove the races with hammer and chisel.The top carrier seems fragile. I applied a little heat and used a proper puller. Oh, and if you leave the cups in the freezer for a while, they'll go in easily.
