i would of marked it but i accidently moved the wheel while holding the other end so it moved!! AH

i'll try post a pic of the shaft but it was wobbling round in the cartridge before i stripped it. surely if its balanced out side the housing why would it matter where it goes?? surely if the wheels are balanced.

edit

the shaft looks ok but i will measure it, maybe the bearings are worn? look scored....would a smal restrictor cause premature bearing wear?
