Annoying Vibration and Rumble

[tweiss3]

Ok, got under it tonight on ramps. Driveshaft seemed spotless, half shafts had all boots in place, and no leaks. The diff (by twisting the input shaft) is pretty tight, some play, but not more than about an 1/8 of an inch. The mounts all seemed very nice, even the front diff mount seemed like it was fresh from a mazda parts box. No tears or anything.

Pictures below, what now? Drain the diff?

Best pic of the rear bushings i could get


My point and shoot decided it wanted to shut off every time i pressed the shutter, so i had to lug my DSLR under the car, which is not ideal at all for these kinds of pictures.
