I've already thought of that - problem is, that those axles haven't seen a drop of oil since they got replaced with polymer bearings - which were to be ruined if they got lubed. Even cleaned them of with acetone in advance to re-installing.
When I switched to polymer bearings I also had the same problem - typically this was caused by the polymer bearings binding and as a result moving the black blocks backwards and forwards, usually resulting in the shorter rod working its way forward until it fell out of the printer.
My solution was similar to the one suggested, but I used these instead: -

I would imagine both could work equally well for you. I'm not 100% sold on using polymer bushings as they do have a habit of binding, but they are quieter and for the moment are working well for me with the block clips.

This is more common on UM3 but has never happened to me on UM2.
I would start maybe with this thing:

Maybe that can hold the rods in better for you.
Also maybe you got oil or grease where they connect to the block. Maybe remove the rods, clean with wd40 and wipe very clean and dry. These don't need much oil - almost zero. The thinner rods go through the head with ball bearings. So you don't want much oil on these. The larger diameter rods in the gantry do need oil.

I'll definitely try that out! Looks like those caps could hold them in place. I'll report the results. Thank you!
