Comment on Ender 3 v3 se y axis bearings loose in carrier.

Personally, I can’t believe there’s not a wedge-centering end-cap or set-screws for dialing in the centering of the bearing just-so, but I’m no expert on this printer.

The bearing is supposed to self center on the shaft with the fitment between the bearing and the shaft. I can’t imagine the pain of trying to manually adjust those very tight tolerance parts for the perfect alignment. Far better to make the housing the bearing goes into correctly from the start.

If the bearing were loose on the shaft, this would be a different conversation entirely.
If adjustment/refinement of the fit in the housing were out of the question, it shouldn’t be made out of plastic, but even in the world of metal-cutting machine tools, adjustment is often neccessary, and if a shim, spacer or set-screw does the job, its what is done.
Meanwhile, my own suggestion was, first, the upgrade kit.
