Hi,
I've had a problem with my power steering on a 98 Grand Cherokee 4.0 (old shape) that has been getting progressively worse. Turning the steering wheel to the left is OK but turning it to the right it gets incredibly heavy, almost like it's locked up. Put a bit of weight on the wheel and it seems to jerk past it then locks up again. While it's happening there is hissing/whining from under the bonnet.
It's hard to tell if it is the power steering going dead (feels like driving a heavy car with non-power steering) or if it feels like its trying to turn against some kind of mechanical resistance.
Drive belt is tensioned, fluid level is normal, there is no crunching or grinding like metal on metal. The problem is intermittent but becoming more frequent. I don't think it's speed dependant, it feels worse at slow speeds but i think that's just because there is less momentum to turn the car. It's had the front axle replaced before Christmas but I had it a couple of times before that happened so I'd doubt if it's related. Front right CV boot has been torn for a while though. I've jacked it up when it's happened and tried turning the steering wheel with the front wheels raised and the same thing still happens.
Any ideas? Would a dying power steering pump cause a problem turning one direction only?
Cheers,
Stuart
