Yes, I agree that it is unlikely. But it's still worth checking just to be sure. However, I just re-read your post and caught the part about loud clunking noises and vibration. A coolant leak isn't going to cause that, so I would agree the technician suspecting the diff. I almost wonder if there is/was an overheating issue with the diff. At those prolonged speeds, the diff might get hot. Perhaps a diff cooler is in order.
