I know I'm hitting this one a bit late but
THANK YOU. That one drives me nuts. It's like when people talk about suspension and say "My fork needs more dampening'. It's damping, not dampening. Sorry for the rant.
By the way, I service sealed cartridge bearings as routine maintenace. I know that they can run alot longer than non-cartridge systems but it only helps increase the life of the sealed cartridge bearing if you flush and repack it. My reasoning for this is that customers usually aren't happy about spending $10.00 or more per cartridge bearing when their are usually four in the rear hub and two in the front. That's over $60 before labor.
