Re: steering wheel hard to turn; power steering fluid is...
Intermittent hard power steering, at the begining of the turn of the steering wheel, once disturbed past the hard part, works normal.
Had fluid change, I notice a sensor, on the control block tower of the rack, is this at fault ? thanks buckleyeng.

to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.
YOU HAVE AIR IN THE POWER STEERING SYSTEM.YOU NEED TO BLEED POWER STEERING PUMP FIRST BEFORE DRIVING VECHICLE.CHECK POWER STEERING FLUID LEVEL ADD MORE POWER STEERING UNTIL REACH FULL COLD MARK..RAISE VECHICLE FRONT WHEELS OFF THE GROUND.START ENGINE LET IT IDLE WHILE TURNING STEERING WHEEL LEFT TO RIGHT NON STOP DONT LOCK OR STOP STEERING WHEEL KEEP TURNING IT SEVERAL TIMES CHECK POWER STEERING FLUID IF LOW ADD UNTIL YOU GET COLD MARK ON DIP STICK DONT OVER FILL POWER STEERING PUMP BLOW A SEAL.IF POWER STEERING FLUID LOOK TAN COLOR SYSTEM FULL OF AIR.TURN OFF IGNITION LET CAR SET FOR A WHILE CHECK FLUID LEVEL.IF STEERING WHEEL FEEL STIFF HARD TURNING DONT DRIVE CAR UNTIL YOU HAVE NORMAL STEERING.IF STILL HAVE AIR IN SYSTEM BLEED SYSTEM UNTIL AIR IS OUT.
bad steering problems,,your steering rack most likely,but,have you recently been stuck in ditch? when wheels are straight, look at front of car when parked. do wheels look funny? one going one way, and the other going the other? may be alignment. is it leaking any fluid on either side of the front of the car? drivers side? passenger side? if it's not out of alignment,,,wheels out of alignment,,the steering rack is the problem. it may be faulty. if not leaking fluid,it may still be bad. first i would make a visual test look under the vehicle while someone turned the steering wheel to right and left while car is in park,emergency brake on!! look at the steering arms while they turn the steering wheel from right to left. no fluid leaks? any resistance in turning the wheel? any leaks,if so,go to leak and repair with steering line replacement.no leaks? suspect a bad steering rack. hope this helps and thank you for choosing fixya.com i love to volunteer

Raise the vehicle so the front wheels are off the ground.
Turn the steering wheel all the way to the left.
Fill the power steering fluid reservoir to the FULL/COLD level and leave the cap off.
Have an assistant watch the fluid in the reservoir while you turn the steering wheel fully to the right and fully to the left at least 20 times.
NOTE: On systems with long return lines or fluid coolers, turn the steering wheel from lock to lock at least 40 times.
Add fluid as needed to keep the fluid level at the FULL/COLD level.
Install the reservoir cap and start the engine.
Center the front wheels and lower the vehicle.
Run the engine for about 2 minutes.
Turn the steering wheel in both directions and verify correct power steering operation.
If it is hard to turn in both directions check power steering pump fluid level. Also with both front wheels off the ground key on engine off, turn the tires manually at one of the front tires and turn with the steering wheel engine off. Check for binding (they will require effort to turn) you are looking for a change in effort.
