The vehicle can be at any temp. I hear it at both acceleration and deceleration, and the sound changes pitch slightly with speed. It is loudest at 40mph on a flat surface, tach at 1500 under very light throttle. To me, the sound is similar to that of a cheap battery-powered R/C car. I'm told it's more noticeable in the back seat. Thanks for any input.
Anything is possible, but I've read that TSB as well and it doesn't sound anything like a whistle to me, and is very noticable to everyone I've had in the vehicle even with the radio turned up a bit. I will definately let the dealer know about that one as well on Tuesday and see what their conclusions are. Thanks again.

It's one of their used cars off the lot. I don't think this is something that they normally do (although I think it should be available for anyone getting service, too) but this is the second vehicle I've bought through them in a year.
That's great the problem was solved. I like hearing that. Talking about rear axles, a couple of years back the Jeep Grand Cherokee's had such bad rear differential noises that the company that manufactured them for Chrysler pretty much lost their business. That was Dana which had provided axles for Chrysler for almost forever. The problem was near impossible to correct because the housings had been machined incorrectly so changing ring and pinion gears wouldn't solve the problem. Chrysler now mainly uses American Axle Corp.
