Here's another way to look at it: I've been told by a person with some experience building turbos that measuring the clearance between the turbin blades and the housing (when deflecting the shaft as far as the "worn" busings will allow), you should see no less than .005"...otherwise the assembly may run too far out of balance and risk contacting the housing sides. Pretty easy to check with a feeler guage.
