whirring noise arse end

hey guys, im getting a whirring noise from the arse end, ive jacked her up and checked both wheels for play, but there is none. i did notice while underneath and small amount of oil on the rear diff, could this be the prob?, on spinning the wheels there was a small rubbing type of sound, lokking forward to your replies.
by the way, she is a 1994 3.9 v8 disco
many thanx gazza

Did you check the fluid level in the diff but sound like the barings are on there way out
