Hard Steering at parking speeds

When I'm parking or even at a dead stop my car wont let the wheels turn unless its on gritty surfaces like sand and dirt etc. I even noticed my CHECK GUAGES light comes on and the car sounds like its stuggling so I avoid forcing it like that if I can. I had the fluid flushed and changed a few months back and it helped some what but still cant turn when stopped. Is my power steering pump on the way out or already dead? Thanks.

It sure sounds like a failing ps pump.

I agree, sounds like the PS pump has given up the ghost. This would account for the engine being dragged down and causing the CEL to light up.

Could be the e.v.o. [electronic variable orifice] stuck or shorted to +12 volts. Not likely though. Probably the pump.

If you change the pump get a cooler while you're at it. Wouldn't hurt to change the rack or get an inline filter if it's metaled out.

Thanks for the input guys, I was looking on ALL DATA about how to remove/install a PS pump and it seemed fairly easy.. is it as easy as the instructions seem? I saw they have one for with variable assist and one without.. if I don't have variable assist and install a pump WITH variable assist.. will I then HAVE variable assist?

No if you don't have variable assist steering you won't have it by just installing that pump. There is a control module and wiring and such. I think the only difference between the 2 pumps is that one has an electronic valve on the pressure line and the other doesn't.

I just read that in the event of an electrical circuit malfunction (short, open) there is a "fail-safe" mode that causes the actuator to provide full power assist. I wonder how "fail-safe" that really is though.

I agree it's probably the pump, and you should definitely get a filter and flush the system before running it normally.

According to coolcats.net since my LS (saddly) doesn't have a 5.0 so then I don't have variable assist. Since I haven't had Steering and Suspension class yet I'm not very certain about everything on it. Would it be not worth it or too expensive to set Cougie up with variable assist and a fresh power steering pump? After Steering and Suspension I could possibly do it myself.. I have access to a lift so it wouldn't be too hard to get access to everything under there. Thanks for helping me out so far by the way!

I don't know about the difficulty as I haven't done it myself nor do I know anyone who has, there's wiring that goes from the front of the car to the back. There's a service connector for it as well as the actuator on the power steering pump, a steering wheel speed sensor (to detect how quickly the steering wheel is being turned), and the control module. It also uses input from the vehicle speed sensor, but I don't know how all this wiring is tied in together. Definitely sounds like it will be an involved project. Perhaps someone who has driven one of these cars with and without EVO will be able to answer whether or not it's worth it.

Hm.. probably is complicated as well as a wiring nightmare I'm sure, I feel my car steers great and I have no issues with the way it is now besides the steering pump issue at parking speeds. Thanks alot for all the infomation, I really appriciate it!
