Squeal when on the gas - drive shaft?

Got a squeal when I get on the gas. No noise when off the gas or going over bumps. I'm guessing it's the drive shaft.

I haven't crawled up under yet. Is there a specific spot to lubricate?

 

Does it do it when you're on the gas in Park?

 

From your description I'd be thinking belt... but if it's clearly not coming from the engine bay then perhaps that's completely off base.

 

That's what i was getting at with my question. Never heard a driveshaft squeal.

 

It's the natural noise the 5.7 makes. Look in the mirror for black streaks on the pavement.

 

That's a great way to isolate belt vs. drive shaft. I'll do that.

Doesn't happen at start up and I'm sub 40k miles so I had assumed drive shaft and not belts.

 

this is the most likely culprit! lmao

 

Update - Sneaking a look under and I noticed the lines on top running into the pumpkin are on a clip. That clip appears to be slightly rubbing on the dirty deeds resonator.

I'll have to adjust it and see if that solves it.
