I just did my first change of the differential fluid while i was on vaction at the in-laws in Lake Charles, Louisiana... . I filled it with Amsoil Series 2000 75-90..... Around town it was fine no chatter or anything... ... I did not add any friction modifier. I had read that most of you guys did not need to add any. Well yesterday, i drove home, about 425 miles just west of San Antonio. When i got close to the house, i could hear some noise from the back end when i would make small turns... ..... So this morning, i pulled out the plug on the diff cover just to make sure i had enough in there..... looked good. So i just drove it around the neighborhood a bit to see if i could hear anything..... nothing to report. Makes me wonder if it only happens once the rear end heats up... ... Should i add some modifier? I will drive it to work tonight to see if anymore noise arises... ...
