He ended up having a new pulley put on and the sound is gone.

wocraig One more thing, I'll probably try pulling the serpentine off and starting her up for a few seconds to see if the sound is still there. If not, then I'm pretty sure that's the culprit. I'll probably do that this weekend.

I'm about to go check my pullies for any damage. Never even thought of this being the source of the sound.
When it idles it's pretty low but the pitch and volume increase and decrease with acceleration/deceleration. Let me know if you see something on your pulley.

Whirring sound and a small crack in the power steering a pulley

A few days ago, my Wrangler sport began to make a whirring sound when accelerating. My dad and I checked under the hood and noticed a small line or crack in the power steering pulley. I haven't seen anything on WF about a wrangler having a cracked pulley, but I saw it a lot on JeepForum with Cherokees. Could the pulley be the source of the whirring? Sorry the picture is so hard to see, but you can see a small line across all od the grooves.
