This sound is driving me bonkers

(I just had my entire rear end done so that is ruled out) Im getting a metal on metal sound, when i accelerate it accelerates, and the same for deceleration. It sounds very thin though, not a heavy metal clunk, but almost like sheet metal grinding. But since it increases as speed increases it must be something in the drivetrain. Ive looked and prayed for little odds and ends but i havent found anything. Im praying its nothing too serious but its sounding like it. Any advice or experience before i throw it to the shop along with an arm and a leg?

The chain in the transfer case may be stretched and grinding against the case. If you put it in four wheel drive and the noise changes or stops that is likely the issue.

also, check the dust shields on all 4 brakes, as well as the brakes themselves

u-joints maybe, or the little ball thing in the CV shaft. (i don't know the name of it)

i had a real bad squeak that sounded exactly as you described. that ball thing was the culprit.

X2 The sound this makes is kinda concerning, I've had it happen more than a few times (rock/pebble jammed between the shield and the rotor), until you get to know what it sounds like it can really freak you out.
