Sooo, I've got a 2006 LE 4WD, fully loaded, and for the last couple thousand miles, it makes a high pitched whine when it's accelerating, in the 1,750 to 2,000 RPM zone. Sounds like it's coming from the engine area to me. This only happens when it's in gear, and especially @ 2000RPMs.

A couple of months ago, I took it to the dealer for an oil change, and the first time, and got the ol' "Technician can't duplicate the symptom". On the way home, I still heard it. Then, 2 weeks ago after another oil change and the same response, I actually drove with a Tech in the car with me, and he definitely heard it. But after 20 minutes checking for loose belts, etc. underneath, they couldn't find a solution. The latest response was "let's see if it gets worse, and then maybe we can pin point it". Sounds like a lazy answer to me.

Has anyone dealt with something similar? Can you give me some insight, and maybe a Service Bulletin that deals with this. I've been digging through this forum for a week now, and can't find any solutions to the problem I'm having. Found a couple of guys that had the same problem, but they never replied with the fix. Any help is appreciated!!!

Thanks,

Rick

Rear differential, really? OK, will do, and I'll report back.

When you hear the whine, let of the gas and see if the whine stops. If so, prob diff going out. Sometime it is hard to tell where the sound comming from.

The whine for sure stops when I'm not on the gas pedal. So if that points to the differential, I'm for sure going to have the dealer look at it tomorrow. Honestly, I don't even care where it's coming from, as long as there's a fix. This squeak/squeal/whine has been killing me! Thanks for the input, guys.
