High Pitched Whine

I think it is the turbocharger. I wish the manual would explain these things better. Thank you.

I would call the noise from the turbo a whistle, or like a distant siren.

Turbo whine comes from firewall - if you open the rear slider window and the whine is coming from behind you, thats probably a pinion or u-joint bearing. Check all fluid levels in drivetrain.

Hard to pinpoint the noise source location. Seemed like it was coming from the engine compartment.

Turbo, if you only hear it during acceleration and/or towing. Normal! Its a GOOD noise...

Got the same under the same conditions. High pitched whine right at the firewall. It changes with engine RPM and scared the BG's out of me. I thought maybe it was fan clutch slipping as the tranny was getting hot and I was going slow. Fan roar I know but this was much higher pitched. I asked around at the dealer and others and no one had a definite answer.

I've only had the 'beast' for two weeks now and only driven it 4-5 times. This morning (as did the day I picked it up...35-45 degrees outside) there was a high pitched whine that mirrorred the engine RPM when the engine was cold. It only lasted for about 3 miles then went away.

To me it sounded like an alternator bearing, but I read something about a belt pulleys wearing out prematurely.

Any thoughts on what this can be. I'm still in my work clothes and may have to try to track down the noise Saturday morning.
