Feel compelled to share this. Steering squeal has gone on for years in my 2003 GC. Siphoned out power steering fluid from reservoir. Took off reservoir (3 nuts, 2 on top and one behind). Cleaned out clogged screen at bottom of reservoir and hooked back up. It wasn't getting enough fluid thru the screen. No more steering squeal.

 

Very common failure point. See article with photos here.
