Steering problem Less that 100K mileage. Steering is all of a sudden hard to the right with a hissing sound. Fluid level okay in pump. Is there a left right steering adjustment on the steering gear box?

the noise is normal your maxing out the hydraulics in the lines [only does it when wheel is turned to max either way] the noise goes away when u release its max position

Sounds like your power steering fluid is low. Steering suddenly becomes very hard, then frees up. Did you perhaps hear a whining noise at the time?. Under the hood, find the power steering pump and / or top up bottle, and check the level. Usually a small dip stick is built into the screw top and marked. Use only correct fluid type.

Most likely the pressure line has a hole.

more than likely it is just low on power steering fluid. system might have air in it now. so after fill power steering unit to proper level driver the car and check fluid level again. and add more if needed . I believe car should have motor running for when checking fluid, same as transmission.

are you leaking power steering fluid? is there any left in the car? normally all you have for power steering is a pump with fluid and an assist ram, if you hear hissing my guess would be that you blew the High end hose in the system, if it happened while driving with little turning such as freeway driving, you wouldn't notice until you got off and were driving slower and making more turns,, check your fluid, if its empty filling it won't do much good until the hose is replaced, but don't drive to many miles as it will end up burning out the pump

CHANGING POWER STEERING PUMP YOU HAVE TO PLACE A DRAIN PAN UNDER THE VECHICLE. SIPHON OUT POWER STEERING FLUID WITH A SIPHONER DONT USE YOUR MOUTH TO SIPHON SWALLOWING POWER STEERING FLUID CAN BE FATAL MAKE YOU SICK.WHEN ALL POWER STEERING FLUID IS REMOVED FROM POWER STEERING PUMP.REMOVE DRIVE BELT.THEN REMOVE THE POWER STEERING PUMP.THEN YOU HAVE TO REMOVE THE POWER STEERING PUMP PULLEY THE NEW POWER STEERING PUMP DONT HAVE A PULLEY YOU HAVE TO HAVE REMOVE PULLEY FROM THE OLD POWER STEERING PUMP.YOU NEED A PUMP PULLEY REMOVER AND A PULLEY INSTALLER.YOU CAN TAKE OLD POWER STEERING PUMP AND NEW POWER STEERING PUMP TO A MACHINE SHOP.THEY WILL REMOVE PULLEY OFF OLD PUMP PRESS IT ON NEW POWER STEERING PUMP.THAT WOULD BE CHEAPER THAN BUYING THE PULLER AND INSTALLER.GO TO AUTO PARTS STORE BUY NEW HIGH PRESSURE LINE O RING GOES TO PRESSURE LINE GOING INTO POWER STEERING PUMP.ONCE YOU GET NEW PUMP READY PULLEY BEEN PRESSED ON.TAKE POWER STEERING PUMP HOME PUT IT ON. BLEED POWER STEERING SYSTEM.WHAT YOU DO WHEN YOU GET NEW PUMP INSTALLED HIGH PRESSURE LINE IN PLACE.PUMP BOLTED IN DRIVE BELT ON POUR POWER STEERING FLUID IN POWER STEERING PUMP UNTIL FLUID LEVEL STOP DROPPING AND YOUR LEVEL ON POWER STEERING DIP STICK AT COLD LEVEL.NOW START CAR UP LET IT IDLE FOR 3 MINUTES.THEN TURN OFF ENGINE CHECK POWER STEERING FLUID IF FLUID LEVEL DROP ADD LITTLE MORE UNTIL LEVEL ON DIP STICK ON COLD MARK DONT OVER FILL.NOW SAFELY RAISE SUPPORT FRONT OF VECHICLE. START THE ENGINE.TURN STEERING WHEEL FROM ALL THE WAY FROM LEFT TO RIGHT DONT STOP LOCK WHEEL .GO LEFT TO RIGHT SEVERAL TIMES.THEN TURN OFF ENGINE CHECK FLUID LEVEL.IF ALL IS GOOD LET VECHICLE BACK DOWN LET IT SIT FOR A WHILE CHECK FLUID AGAIN.DONT DRIVE VECHICLE IF POWER STEERING PUMP MAKE NOISES OR YOUR STEERING FEEL STIFF HARD TO TURN.JUST MAKE SURE FLUID LEVEL RIGHT AND DRIVE BELT TIGHT GOOD LUCK.

YOU NEED TO BLEED POWER STEERING SYSTEM BY HAVING LOW FLUID AIR ENTER THE SYSTEM.PARK CAR ON SOLID LEVEL GROUND SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS.YOU CAN LEAVE CAR ON GROUND BUT TURNING STEERING WHEELS BACK AND FORTH WILL WEAR SPOT IN TIRES.TURN STEERING WHEEL TO THE LEFT WITH THE ENGINE OFF.CHECK POWER STEERING FLUID.ADD MORE FLUID IF LOW.MAKE SURE FLUID LEVEL ON COLD MARK ON DIP STICK.THE YOU CRANK CAR UP LET IDLE LITTLE HIGH FOR 15 SECONDS.THEN TURN OFF ENGINE.CHECK POWER STEERING FLUID LEVEL MAKE SURE ITS ON COLD MARK AT DIP STICK.THEN YOU START THE CAR UP WHILE IDLING TURN STEERING WHEEL IN BOTH DIRECTIONS SLOWLY TO THE STOPS DONT HOLD IN STOP TURN STEERING WHEEL LEFT AND RIGHT FOR SEVERAL TURNS.STOP ENGINE CHECK FLUID IF FLUID TAN STILL HAS AIR IN SYSTEM.LET CAR SET A LITTLE WHILE TRY THE BLEEDING PROCEDURE AGAIN.THERE IS A REASON POWER STEERING FLUID WAS LOW CHECK ALL POWER STEERING HOSES AT POWER STEERING PUMP TO THE RACK PINION ASSEMBLY.

I assume you've checked belt condition, belt tension, as well as fluid level?

check your power steering belt. it may have broke or slipped off the pulley. if it seems ok check your fluid level. if it is still at normal operating level for hot or cold then your power steering pump may have just seized up and you may have to replace it.
