Exclamation Screeching Turbo??

Returning from a week of pulling the 5er the 6.0 started developing a fairly loud screech on a hard decel. At least that's the best I can describe it. It throws NO codes, hard nor soft. It's going in as it still has a year left on warranty, but anyone wanna hazard a guess?

Hard decel = accelerate quickly, then back off the go pedal. It sure isn't a turbo fart...not one I've even heard before.

You sure it wasn't coming from the passenger's seat Bud? I've gotten a screeching sound from that area on hard decel a time or two.

I just drive with the right side hearing aid removed!

You guys may have hit the nail on the head..... I didn't hear the fan come on going over that high pass near Hazelton, PA!!!! Could that be why?

I know that, but it seems cheaper than Divorce!

Could the sound you are hearing, be from the fan locked, when sudden Decel, and fan spinning faster than the belt making a squeal? Had a Log Skidder that did this all the time. Fan going faster than the engine=screach from the belt.
