Steering problem, can turn left w/ powersteering assisting but when I turn right I have no powersteering assistance

at this point I would suggest that there is a problem with the directional valves in the box or hose condition as the pressure for the right is the same as for the left
it is not getting that pressure through the valve to assist with the turn
have an accredited steering specialist shop check it out

Some Saturns have electric steering assist and they have a module on the steering column under dash.

Its there for good reason, so you dont spear of the highway at 65 mile an hour, it deliberatly lowers stearing preasure/ assist at higher speeds. and in four wheel steer modles it switches from opposed rear steer to aligned rear steer. so i sugest unless it is broke dont remove it.

bleed power steering with engine off pour power steering fluid in the power steering reservoir until fluid stay at full mark on powersteering pump dip stick.wait few minutes then check powersteering fluid again if low add little more when fluid level stop dropping crank vechicle turn steering left to right with out a stop turn steering wheel all the way to the left to all way to right for minute until air bubbles leave the powersteering fluid. when steering wheel feel normal stop engine check check power steering fluid should be at full hot mark if fluid level dont drop air is out the system. dont overfill powersteering reservoir if so you will blow front seal.dont drive vechicle if steering dont feel normal have vechicle towed in garage.

If you have the hydroboost system..The powersteering pump gives you power assist while you steer..And it also gives you power assist to your brakes..When you have trouble with the power steering pump,,you lose your assist in your steering and your brakes..Youll get a hard brake pedal feel and it will be hard to steer as well

this is the problem occur the less quantity of oil in your power steering plz check the oil level and maintain it

power assist come from power sterrig pump
brake master cylinder produces brake pressure
if no pwer assist check power sterring fluides and lines
assuming the pump is good do to steering o.k.(not mention)
if no pedal pressure check fluide level top up and depressed sevral time then check for leakage if nothing found may be flowing back to powersterring reservoir check to see if level whent up

Hello hummelsautob.
Changing the power steering cooler can't allow air into the brake system. Two different fluid systems.
Your F250 has it's brake assist powered by the power steering pump.
Instead of using a vacuum assist it uses the hydraulic power from the pump.
When refilling your pump you have gotten air mixed in with the fluid. This turns it into a consistency something like whipped cream.
When in this state it isn't effective. Let it sit for a couple hours and let the air bubble out of the fluid. Recheck your level after this as it will drop.
This will make your brakes feel normal again.
Just a note on adding fluid to an empty power steering pump.
Add fluid to the reservoir but not to the top, turn the steering wheel back and forth slowly with the engine off. This will keep the fluid from foaming.

check the power steering pump, if its good than it will be rack and pinion issue. the pump create a high pressure to help assist with steering, and the rack and pinion work like hydraulic cylinder which receive the pressure from the pump and the steering work like control valves. by turn left or right you controling the pressure to make the wheels turn either right or left. check and see if you have any leaks.

You have a failed steering rack, this problem is caused by a defective seal inside the steering rack, you need to replace it, make sure you flush the PS system, as it will most likely be full of debris from the failed rack unit.
