If anyone with a wrangler has had issues getting rid of a squeaky belt noise and no one has any answers at all - I may well have it.
For over a year I had a belt squeak that couldn't be stopped. I did the obvious by replacing the belt - 5 times unfortunately. I replaced every single pulley as well and still no change.
Turns out there was a misalignment that no one had seen or even looked for. The A/C and power steering pump pulleys are attached on a bracket mounted to the sidewall of the engine in TJ's
Apparently they had shifted at an angle over the course of 12 years.
So if u can't get rid of the squeak then check your pulley alignment
