What the heck is going on? Bearing or CV Joint?

[amalventano at sc.rr.com (Allyn)]

hmm, never know, the symptoms sound like a wheel bearing (happens during 
turn, etc). could it be a rear bearing perhaps? i know bearing noise is very 
difficult to localize while driving. i had a bad front bearing trick me once 
(thought it was the side opposite of what it really was).

inner cv joints usually make a clunky/chewey kind of sound, and bearings 
make more of a whine (kind of a very slow motion grinding sound). in both 
cases the sound follows the speed of the car.

as for that inner race, you only need a press and the right bearing tool to 
grab it and yank it off. would have took like 5 mins.
