Default Metal to metal noise in rear when turning right only!

The title says it all. Only when turning slightly right. A bit louder under slight acceleration. Not in differential as a mechanic suspected - rebuilt that - same noise. [car is an 05 GT]
Coming from lower rear. You can hear it /feel it in the floor. I'm thinking trailing arm bushings or the weird upper link. Is this a common problem?

Sorry I didn't spell METAL correctly.

Wild-*** guess because I have no idea what kind of metal-to-metal noise you're hearing . . . check for an exhaust line rubbing somewhere because it sounds like something is either moving sideways or up/down depending on which way the car is rolling. Aside from the suspension linkage, exhaust is the only thing that moves at all.

That's the best I can do.

The noise does sound like a exhaust pipe hitting, but that is not it. Also could sound like a backing plate or an ABS sensor touching a rotor but we have checked that out too. By sweeping right and left gently with the steering wheel you can turn the sound on and off like a light switch. It is a grinding gritty sound, like metal to metal. It resonates through the rear floor. I am thinking of looking into the control arm above the differential. Can I drive the car on a test run with that arm removed? [ asking this as I see a panhard bar for centering the housing]

Don't even think of trying that. The upper arm is the only thing that keeps the axle from pivoting about the LCAs and potentially making a real mess back there.

OK, I figured. THANKS for that info.

I would like to start replacing bushings. Maybe upper control arm first and see if noise is gone. Then LCAs. Around here I can't buy bushings by themselves, only on E-bay. Any suggestions as to where to buy?

I had a similar sound in one car-caused by the dust shield. It was slightly bent and hit the brake caliper when I turned right. It was pretty easy to spot-there were scratch marks on it.
