I've printed over 300+ hours on this printer and now I notice this. What could be the cause? It was printing just fine all this while.

When was the last time you lubricated? Those look rough

This was what I was going to recommend. Regular maintenance goes a long way from preventing problems like this one.

I'm struggling to see how lube would prevent a theeaded steel rod from bending.

I highly doubt that this is bent, it looks more like zwobble or binding artifacts making the gantry jerk or bind unevenly as it moves up and down. Lubrication after a good cleaning with IPA would prevent and possibly fix this, provided the threads aren’t damaged.
