[s-cars] got a new sound

[Wayne Dohnal]

I've got a similar situation with a vibration except I feel it and don't 
hear it.  I ran the car up on blocks and didn't detect anything in the wheel 
bearings or axle CVs.  As much as I hate the prospect of it, I'm about ready 
to replace the center bearing and regrease the CVs on the driveshaft.  My 
center bearing support is sagging, but not torn.  I just hate the part about 
dropping the exhaust system.
