The CV grease from your swivel joints is leaking past the oil seal into the axle housing and contaminating your diff oil. It's nothing to worry about as far as the diff is concerned. However, at the least, it probably means your swivel joints need topping up with CV grease. You can buy it at Halfords. Use a plastic syringe to suck it out of the tin and inject it into the swivel housing (375ml is the required amount from dry). If the oil seal is very bad you'll need to change the oil seals, but it's a big job and if you doing it you might need to change other parts at the same time.
