Outers usually clatter in a clickity clack fashion when turned tightly, inners usually rumble when they go bad, which they rarely do.
I think I'd put the hood up and brake torque it in gear, see if the motor is flipping up off a broken mount...fore and aft roll (slight) is normal, the restrictors on top control that and you can see if they're broke just by looking, but if the motor "crawls" diagonally or lifts one end more than the other under torque, something broke...
Try it in both drive and reverse, so you don't miss anything.
