Which higher quality bearing did you use?
Re crush tubes did you use a shims or an actual tube of the right length?
You need 1.65mm spacing between the bearings, and a 0.2mm shim between the pin and outer bearing so that the hex clamps the whole thing into one solid assembly (while still allowing the bearings to rotate of course!).
I use these plus a 0.2mm shim between the bearings, its the closest I could find:

The bearings were just some random ones off ebay, but had less play than the ones that came with the shafts.
