Limited slip

My 87 monte carlo ss is making a grinding noise with a rythmic “clack” when i drive. It has a 7.5" 10 bolt w/ limited slip 3.73 gear ratio. I pulled the cover but cant see anything chipped or worn (can only really see the ring and pinion). How do I check the limited slip? There was no large debris in the fluid.’.
