Hello all!

I drive a 2000 4.0L Cherokee Sport. For a while now I've had an intermittent drip of PS fluid coming from under the hood. A day ago I was driving home and heard a whine, especially when turning. When I got home I noticed the drip was now leaking steadily. It seems to be coming from the junction of the Pump and Reservoir. I removed the pump and the o-ring at the connection was perfectly intact, and lubricated with P/S fluid. I put everything back in today and it started leaking again just as badly. In addition my serpentine belt also now makes a squeal every time it goes over the pump pulley. It goes away at idle if I squirt some water on it making me think it's possibly belt related also. I've tried tightening the belt and loosening it, to no avail. Tightening it yields a steady squeal while loosening it makes it seem to only squeal as it rounds the ps pump pulley. I'll try and add some pictures to show the leak, I would greatly appreciate any insight into where it might be coming from if I'm incorrect and what I should do about it. I'm leaning towards replacing the pump/reservoir although they both look intact as well as picking up a Gatorback. Is it possible the clips that hold the two together are bent or miss-aligned causing the leak?

Thank you very much in advance for any help you can provide.

Also sorry for the awful camera phone pix

 

Bump, hoping someone has an idea. Planning to just replace the pump and reservoir and get a new pulley.
