Is this something to be concerned about? Differential?   Michael CJ (Hughmungus) New Member Username: Hughmungus Post Number: 13 Registered: 07-2003 Posted on Thursday, January 15, 2004 - 12:02 pm:    Oh, yeah gets real loud when accelerating at highway speeds.   flyor (Flyor) New Member Username: Flyor Post Number: 22 Registered: 05-2003 Posted on Thursday, January 15, 2004 - 12:31 pm:    Is your mother-in-law back there?   Andrew Maier (Newman) Senior Member Username: Newman Post Number: 503 Registered: 04-2003 Posted on Thursday, January 15, 2004 - 12:51 pm:    That one never goes out of style... Most Disco's whine from the diffs. Seems to be one of those "character traits." Granted, it could be something, but if the truck is maintained properly and doesn't have, say, 300,000 miles on it I'd say you're probably fine. Turn the radio up or get MT tires.   mark gomez (Mark) Member Username: Mark Post Number: 49 Registered: 05-2003 Posted on Thursday, January 15, 2004 - 01:33 pm:    Check your diff fluid too. Mine is dark grey after two months which leads me to believe that my rear diff is starting the checkout process. Front and transfer case is still gold though. I was hoping that it would last a little longer so that I can buy a bumper but hey, things don’t always go “as planned” so I’ll be doing diff shopping soon. Maybe next year on the bumper. Good luck - Mark
