Rear End_Tech Question/Help

[squares98]

My Mustangs Rear-End was completly rebuilt by a Ford Dealer recently and there are problems.
When I have it on jack stands I can rotate one wheel from 12 o'clock to 2 o'clock before the other side engages, with a noticable clunk.
I think this is the same clunk i hear pulling away from a light, shifting, and short turns(Into a driveway for example).
The sound is inbetween a Clunk and a Click.

Any Ideas?

*The Car is going back in tomorrow under warranty/bring back.

Missing the rubber O ring that goes next to the "C" clip.

it could just be the basic driveline in the axle clunking together, that lil gap between the gearing of ford's imperfection

quick question about rear end fluid. if my car shakes and like kinda spudders durnin certain gears and i havent changed my tranny fluid/coolant stuff or my rear end fluid, would changing those make a difference or could that be like my rear end goin out?

UPdate:
The wheels dont turn as much as a though before moving er side, it seems within tolerance like tomustang said. However I did notice that the passenger side axle has about 1/10" play while the drivers side is snug(~0.03"), from searching that seems normal as well? maybe I just need a synthetic fluid change< i noticed with my last gear set that really quited things down alot.
