How to replace power steering pump in 2000 Plymouth Grand Voyager

As the two systems are not connected in any way, I would call it an odd coincidence. The power steering is a hydraulic mechanical system that routs fluid pressure created by the power steering pump and signals are input from the steering shaft to the rack n pinion. And the wipers are electric mechanical that takes the power from the electric wiper motor controlled from the wiper switch to the wiper transmission which moves the wiper arms.

Never brake fluid and nothing else goes in brake master cylinder.

Put power steering fluid or automatic transmission fluid (dextron)

I suggest you to replace the power steering rack. You can get Power Steering Rack for all Plymouth models at http://www.carsteering.com/steeringparts/Plymouth/Power_Steering_Rack.html

Power steering fluid.Power steering pump is on backside, and hose runs to it.

check the 2 lines that go to power steering pump for leaks

You just have to take the pasenger tire and the dirt guard to get too it, Remener to lose the elt 1st.

belt is cheap. power steering pump is cheap (find a good used one a salvage yard) power steering rack is a bit more expensive and more involved to replace. you really need to know what is bad. make sure the fluid is full first. any noises?

the bolt that the locknut is on may also be tightened up to hold the pump
loosen off that bolt a turn or 2
