This Squeal is pissing me off!

[nkostop]

There is a very annoying squeal that is coming from my 99 Yukon 5.7...... I have changed my idler pulley, tensioner, belt, and harmonic balancer. Any ide as of what it could be I'm so sick of this problem.

It can often be hard to locate that stuff. Most times it's not coming from the area you think it is. I chased one for awhile and even went as far as replacing my AC compressor. Turns out it was the bearing on my power steering pulley.

**Update** So apparently there are two different size alternaters for my truck and I have a smaller one. That being said the belt sizes are different, so I changed to a smaller belt, and NO MORE SQUEAL. Thanks everyone for the help!

Best belts to replace with is the Goodyear Gatorback belts you can get at Rock Auto unless you have a source in the area.
