I have replaced my PS pump...didn't fix the whine.   I saw that the hose with the pressure fittings on both ends that comes out of the front of the pump and runs around into the back area of the fan had some fluid leaking out, so I replaced the O ring...did not stop the leak.

So, I replaced the hose entirely...stopped the leak, but did not fix the whine.

Yes...I have plenty of PS fluid in the reservoir.

The power steering is actually working, but it whines all of the time and worse when I am turning of course.

Anybody have any idea what I am missing?    

I have the same problme..i replaced the pump from a small leak  bought it got it put it on..then the small leak ( about a teaspoon every day) was still there  so i replaced the high pressure hose..which FYI was a diffrent fitting that attached to the pump itself. with a new ps pump on and a new high pressure hose on no leak i get a weak whine and the fluid seems a bit cloudy..ti have a question about the new fitting jeep now uses..do you take the adapter attached to the pump off and thread it directly into the pump?...i have no idea there is no info on it anywhere..amazing..ill never buy anbother jeep this jeep has 60k on it garaged kept all service to the T..wife drivven not harsh driving and its been a night mare keeping it running  fuel pump.tuen-ups tranny fluid changes u name it its a problme...  

Try sucking some of the fluid out of the resivoir then replace it with lucus power steering fluid stabilizer. This stuff is amazing may take a 100 miles or so but you will see a difference.         cj784 thanks  

Hey guys I'm new to the forum. Just looking for some help with the my power steering pump. I have to replace it. I was wondering if you could either tell me how to do it (or if I should pay someone to do it) or show me where I can find out. It is a 01 Grand Cherokee V8. Any help is much appreciated.
Thanks in advance.

is it noisy???? leaking.????  make sure its not a hose or the steering box first..


that really looks like an easy one...

Siphon power steering reservoir.

Remove the cooler return hose at the reservoir.

Disconnect the pressure hose nut at the pump.

Remove the pressure hose at the pump.

Remove serpentine drive belt.

Remove 3 pump mounting bolts .

Remove pulley from pump if necessary.  

I have a 2002 4.7 V8 Grand Cherokee it whines all the time when i turn the wheel, I think its normal, although i read a Mopar site on powersteering pumps on the WJ and it said that not using the manufacturers PS fluid will damage the system this weekend im probably gonna siphon out the old fluid and put Mopar brand PS fluid and see if it makes a difference.    

How do you remove the pulley
