Use a mechanic's stethoscope - far safer if you are going to do this.
In fact, it's what my mechanic said they do since 'the sound bounces
around and you can't tell where it's coming from '.
I did one of my bearings myself and guessed right... it was the LOADED
bearing. But bear in mind that these bearings have two races, so
you can get the situation where cornering can cause it to be
louder when unloaded.
