Actually... In my experience the weight of the lubricant has had not effect
on wether the rear end makes noise or not.
Jason, you may want to find out if the shop added the fristion modifier back
into the differential. That could cause the noise. Do you hear it around
corners and while parking? It would be sort of like a howling sound.
The reason that I bring this up is that the 3.55 unit I've got is a LSD and
would assume that yours would be the same, now just with 3.92 gears on it.
I'd start there.
