[FC] Differential side bearings

[Charles]

Thanks to all of you for the great info. I couldn't get the floor panel 
off last night because I didn't have my long socket extension. I did 
however, jack the wheel off the ground and had a listen during the 
quieter hours of the evening. That axle bearing is definitely noisy and 
some minor scraping sound as well. I can see how putting some weight on 
the wheel would amplify that scrape. When I put my ear as close to the 
diff while turning the wheel it seemed pretty quiet except for a 
soft/muffled klunk that was audible several times per rotation (I did 
not have the presence of mind to count the number of times per 
rotation). My next step since I'm not much of a mechanic is to pull out 
that axle bearing and have a peek inside to see what I can see. I'm 
sourcing out a local used bearing/axle.

Thanks again everyone, I may not be able to post until tomorrow evening.
