Rear Diff Clonk

Hey all in my RA since I bought her in 08 it always had a slight clonk out off the rear diff when DCCD set to fully open normal setting but since last year I think it has got a small bit louder seems too happen when turning slow either right or left on/ off the power I have changed to the motul 90pa LSD oil from the subaru genuine diff oil Motul 90 PA Lubricant limited slip differential (LSD) Extreme pressure and has seemed to help it however trying to make myself feel better by reading this forum Rear diff clunk / knock - Subaru Impreza WRX STI Forums: IWSTI.com hope its not serious and I need to change diff or do the diff generally get a bit louder over time? or is it with no sound deadening you hear every thing in these cars and I shouldnt worry about it? 135k kms /83k miles on her and dont go mad in it well kept, your replies would be great thanks

You should hear the diff in a rally car turn slowly in tight circles. I assume you're is a plate diff in the ra
