M.B. Doc: I see you have lots of experience in the MB field, so I'll run this one by you for your comment. I bought a new ML500SE in Dec. of 04. From the first time I drove it over 65 mph I heard a high pitched gear whine under deceleration from 75 down to about 68 mph. Also a different lower pitch gear whine under load from 40 up to about 65 mph. I can make these noises go away by playng with the throttle. My shop foreman tells me I have an AWD vehicle with aggresive tires (Dunlop SP5000) and doesn't want to open any differentals. I've built enough gears for racecars in my life to know gear noise when I hear it. Is this a common problem on the ML's or just an isolated case. I had an 00 430 prior to my 500 and it had no noise. It had Dunlop Gran Trek 35's on it! Any comments?? Thanks
