I'm told its cuz it has a gear drive trans case, its not terribly loud just always there...checked and changed lube, just to be safe. It didn't have a lot of metal on the drain plug...just a little. Is this normal?   Dean Chrismon (Chrismonda) Member Username: Chrismonda Post Number: 75 Registered: 12-2002 Posted on Tuesday, March 11, 2003 - 04:12 am:    It is normal, to have some metal flakes. Did the fluid change help with the noise?   Joe Still (Joedisco) Member Username: Joedisco Post Number: 61 Registered: 09-2002 Posted on Tuesday, March 11, 2003 - 01:20 pm:    I've been looking into this for several months. General consensus is it is normal. I can tell the tcase by slightly letting up on the throttle to zero thrust and it goes away. The rest is tire noise. Some posts say Royal Purple or other syn lube helps or works. Doubtful it'll stop it but can't hurt. Someone posted that it was an option called MILS. (Mother-in-law silencer)
