2 thoughts are you sure it's the diff? A problem with the axles can make noise the fix is it pop them out of the bearing and lube the splines. The other thought I have is your clutch plates in the diff are noisy. Try driving a couple tight circles in each direction to drive lube into the plates. I used Valvoline 75 90 synthetic gear oil with a tube of GM limited slip additive in my diff. Per RPM transmissions recommendation
