No danger but inconvenience and it will eventually clear up with time and
miles driven.

Joe,
What 'outer' bearings are you referring to? The ones that the outer axle
stubs ride in? If thats the case you didn't change anything in the gear
mesh and your noise is something else. If you're talking about the carrier
bearings and or pinion bearings, and you didn't reset/check for the proper
running clearances than you have a BIG problem. No matter what anybody says
you can't simply replace the bearings without setting up or checking the
rear end to check for mesh and end float (backlash). The bearings WILL be a
different thickness, however slight. You may get lucky and they would still
be in tolerance, but it's been my experience that they won't be. Iv'e set
up MANY a rear end and I can tell you if you change pinion bearings YOU WILL
HAVE TO RESET FOR GEAR MESH PERIOD! If you are simply changing the carrier
bearings than all you will have to set is backlash, as gear mesh *should* be
O.K.
Your noise will NOT go away if it is in fact gear noise. Noise is wear.
Wear is generating heat, and pre-mature faliure. Were not talking about
next week, next month, or even next year (unless the noise is really loud)
but decreased overall life of the unit.
