Bernie describes the early audible signs as "clicking and clacking". 
Chris tells me he heard a "clanging". Both kinds of noise  fail to 
describe  my car's driveline noise, which I'd characterize as a 
low-level, metallic scraping (or rubbing) sound that's heard only 
while coasting (off-throttle, in most gears but not 5th).

I've been thinking it may front differential-related, but the 
location of the sound is difficult to pinpoint. So, I wonder if it 
could be coming from the center CV-joint bearing that is being 
discussed here. I suppose I could just try the "r&r cleaning and 
relubing process" Bernie suggests. Anything especially difficult 
involved in this? Is it just a matter of pulling back a rubber boot 
and packing in more lube, or...?
