Power Steering Pump problems of the 2004 Jeep Grand Cherokee

Tl the contact owns a 2004 Jeep Grand Cherokee. While operating the vehicle, a grinding and humming noise was present from the steering column. Also, the power steering assist suddenly malfunctioned and caused the steering wheel to become very difficult to turn in either direction. The vehicle was taken to an independent mechanic who diagnosed that the power steering pump and hose were faulty and needed to be replaced. The contact indicated that the vehicle was repaired on four separate occasions, but the failure continued. The manufacturer and local dealer were not notified. The failure mileage was 88,000.

Steering losing power when turning right, accompanied by a whine and sounds of pressure loss. No leaks in power steering pressure hoses, no leaks in gear box (gear box was dry), no leaks in any other relevant parts within the steering system. Problem was investigated by aaa and pepboys. Power steering pump replaced and flushed on 6-Jan-12. The loss of power steering problem is still persisting, and is worse now with a new pump and clean pump system. Pepboys national research indicates that the problem is within the gearbox, spacer clip moving out of position when turning right cutting off power to the steering system, and moving back into position when turning left restoring power to the steering system. Chrysler has a TSB reported March 4, 2003 for this exact failure. Chrysler claims this vehicle's VIN is not included in the manufacturer's TSB, NHTSA campaign number: 03v079000. Case has been opened with Chrysler - case #: 21743619. I cannot steer this vehicle at all without the assist of power steering. Extremely concerned with the potential danger of losing power steering while driving causing a crash, flipping, and potential serious injuries or death.

I own a Jeep Grand Cherokee 2004--the problem I am having is with the steering. It is very hard to steer to the right the wheel locks and I cannot turn. I took the Jeep to hayes Chrysler Dodge Jeep and was told I needed a power steering pump and pressure line and a power steering gear box. The total quote is $1601. 00--I could not afford that so I took it to midas and they advised me there was a recall on this part and Jeep should replace the part free of charge. I pulled the recall notice and it does state to take the vehicle to the dealer and it would be replaced. I was told by the dealer and also Chrysler that my vn # was not on the recall list. . . . I am very upset because my vehicle is doing the same thing as stated in the recall but since my VIN number is not listed they cannot do anything. Please advise me what ic an do at this point. When I first purchased the vehicle I took it back the same month and told them something was wrong with the steering I do have documentation. I also took it back a 2nd time and they told me they could not find anything.
