I can't imagine by lifting the entire rear both sides. Having someone else spin the wheel and then placing my hand on the cv by the trans or the wheel the result would be different. Short of a stethoscope and a hunch its seems to be a problem of subtle nature .ALthough its loud in the cabin, not so subtle.
A more experience person should look at it as opposed to me throwing parts at it.
Does anyone have an idea what it would cost to have a mechanic replace the wheel bearings, or do they just replace the cv's as well because they are there?
I am going to try the feel thing as ROnnie suggests this weekend before I make a final decision as to how to proceed
As far as the sound that some people have asked about it not a grinding sound. Its just very loud in the cabin as my original post stated. ALso the sound happens at 30 to 50 mph. Maybe this is why spinning the wheel by hand is not diagnostic. WIth the clutch out it sound like the wheels are the source
Everyones final thoughts would be appreciated

you probably wont hear or feel it spinning it by hand. you need to run the engine and put it in gear. even then it will be subtle. you really have to just know what a bad bearing sounds like and what a CV sounds like.
driving the car the bearing is going to be a "roaring" sound. CV's usually click or pop. again, never heard a bad 911 CV.
putting it on stands and checking really just verifies which side and the fact it is not a tire.
just went thru this with my 930. left side was bad but did both.
I also did my CV's before this. I had one CV that had pitting, no sounds from it and I certainly did not suspect it was a CV,.
if you are still in doubt, take a mechanic for a ride.
