[TowerTalk] Rotor on the verge of failure?

[Bill Aycock]

Tony-
If the assembly includes a "thrust" bearing, particularly a TB type, check 
it before doing a lot of rotor work.  The Aluminum race- steel ball type can 
go bad and give lots of peculiar noises.  The balls pit the race, even when 
the rotor is used very little, and rotation makes clicks and pops.
