Today i changed the UDT fluid in the front axle of my 2001 L3000DT. The owners manual says it holds 6.3 qts. After refilling with 5 qts. it showed full on the fill plug dipstick. Drove it around for about 15 minutes and then parked it for about an hour. Rechecked and added a little more than another half quart. Other than keeping an eye on it the next few uses should i do anything else? Any information is much appreciated.
