Today i changed the UTD fluid on the front axle of my 2001 Kubota L3000DT. The owners manual says it holds 6.3 qts. After replacing with 5 qts it showed full on the fill plug dipstick. I drove it around for about 15 minutes and then let it sit for about an hour, rechecked and added just over half a qt. Other than keeping an eye on it for the next little while is there anything else i should do? All advice is much appreciated.
