This could be the problem. When this system came out in the 97's they had a lot of problems with them. Question, does it really get wild steering going down the highway? Owners said it would get really hard to steer then get real loose. Good luck. Normally just when I am stopped trying to back up or park
NV7 is with Variable Effort Steering. N40 is with Non-Variable Effort Steering. Check the "Service Parts Identification" sticker for your car. Variable Effort Steering will have an electronic control valve on one side of the power steering pump with an electrical connector. The Variable Effort Steering "EVO" valve adjust the amount of power steering assist. It is intended to make the steering stiffer at higher speeds. This helps prevent the vehicle from wandering at highway speeds.
A front suspension system has excessive steering effort and rapid steering wheel return. The most likely cause of this problem is
The Chrysler LHS comes standard with a speed proportional rack and pinion power steering assembly.
There is no simple, automated, way to do this; you just have to do an effort to understand the problem.
The front suspension may have excessive positive camber

An independent variable is the factor that is manipulated by the experimenter in an effort to study the effects of the change upon the dependent variable.
The only dangers that might arise from driving a vehicle with a failing power steering pump is burning up/breaking the belt that is driving the pump IF and ONLY IF the pump seizes up. The other problem you might have is the increased effort to steer the car. As long as the increased effort while driving is not a problem you can at least drive it to a service station to get it repaired.
The problem with this concern could easily be the steering gear. The power steering pump is responsible for providing fluid pressure but the steering gear will provide steering assist with the fluid pressure depending on steering wheel input. with the front wheels suspended and the engine off with the pittman arm disconnected from the steering gear the wheels turned left to right by hand at the tires should turn with the same effort both ways. if not, the concern is within the suspension (ball joints) or steering someplace. If the steering effort is the same suspect a steering gear fault.
There are more than one. The computer card that controlls the air suspension as well as the variable effort power steering is located in front of and slightly below the glove compartment. You can remove the glove box and the reach in and access it.
