Grinding noise in rear

Grinding noise in rear
Hello, I have a 2000 Mustang (101k miles, second owner) that has a grinding noise coming from the rear. The sound is constant and unchanging in all speeds.
Here is where I haven't been able to find help via web searches: the sound stops when the clutche is in. I can coast almost silently.
When I had a shop look, they said it was likely the differential but that it could be anything from a small fix to a huge problem. They also couldn't tell me if the $1300 they quoted would even be the problem, or if it was a host of other problems.
Thank you in advance for your help.

It does sound like it could be in the differential. If you are sure it's coming from the rear, it is likely your differential input/output bearing. When the clutch is in, there is no load on the bearings and they will spin without the grind sound.
To determine the location, jack up the rear of the vehicle put it in gear and use a diagnostic stethoscope. I'll bet when you touch the diff, you hear lots of sound... not too bad to fix, but does take a good bit of work.
