rear end growl

["Freese, Ken" <Ken.Freese@Aerojet.com>]

I have a bearing growl that improves a little bit as I initialy drive a
block or so. I changed a rear wheel bearing with no difference. With the
hardtop on, it is emphasized that I need to take care of this ASAP. To
pinpoint the noise, must I take a rear seat out and listen? I was thinking
maybe the pinion bearing?
Thanks for any suggestions.
