Hey Banj, many thanks today for your assistance in changing the oil in the rear diff on my Freelander, much appreciated. I have been doing some research on the IRD unit and it uses 1.1 litres of 75w-90 oil same as the rear diff, so we could have changed it as you suggested. If its not done in the service at ALL FOURX4 in a couple of weeks, I will get some more oil and do it.Apparently, there is a drain plug on the IRD unit, so the oil will not have to be sucked out. I'll check with ALL FOURx4 about changing the oil in the IRD unit.
