My 03 has a 10. 5" and a limited slip 3. 73 ratio. From 0-3 mph there is a shutter so bad it shakes the mirrors so you can hardly see out of them only when turning slightly either direction. Straight on it fine and above 5 mph or so its fine. Only just as I take off. The dealer said it is a standard occurance for "this type of rear axle". I dont believe it because it didn't do it until after they installed a new ring & pinion. I assumed it needed to be driven some to "work" fluid back into clutch plates as they were cleaned off when out for R&P. But there are no plates I find out now and wondering what to do. Is this a normal thing for any of you?
