Looks like it is your High Pressure power steering hose gone bad, it will squirt more fluid as you turn the steering wheel. Replace as soon as you can, if that fluid lands on the engine it can easily ignite a fire under your hood, happen to me some time ago when my car began to leak power steering fluid from the high pressure hose and the oil got all over the hot engine, it ignited causing a engine fire. Power steering fluid is very flammable and dangerous when it is close to excess heat from the engine. Most power steering systems have a low and high pressure hose, the high pressure hose takes tremendous hydraulic pressure every time you turn your wheels.
first check the condition and level of p/s fluid. if low top off first and turn your steering wheel left to right and back several times to try to bleed air out of p/s system. if p/s is still stiff or hard your p/s pump pressure output can be measured with a pressure gauge. if pressure is below specs its time to replace it. if your p/s output pressure is good then you would need to inspect your p/s hose or lines for kinks or restrictions to your steering rack. on certain model vehicles p/s sensitivity can be adjusted on the steering rack. you would need to check the vehicles service manual to see if its possible to adjust steering rack sensitivity.
power steering hoses run from pump to the steering box, (high pressure) and from the steering box to pump (low side).. is a closed connection. pump to box, then from box back to pump. High pressure should have pressed on fittings, while low side may have normal water hose clamps or replaceable hose without pressed on fittings.
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.
There is a "pressure regulator" located in the pump just behind the high pressure line that directs high pressure fluid to the steering rack when you turn the steering wheel. It sounds like the regulator valve is sticking and not sending the high pressure fluid to the steering rack when you turn the wheel.
You can remove the pump and clean the valve, reinstall the pump and flush the steering system with fresh fluid or replace the pump and flush the system with new fluid.
Okay, so you have either a pressure line that is leaking, or a bad pump, bad seal, or bad fluid cannister to pump seal. Does it make any noise when turning the wheels? And have you checked and had to fill the resivoir with additional fluid from time to time? The fluid can be washed off the housing, frame rails, driveway, ect, with degreaser and strong water pressure. But, you need to check the cause of the leaking. Overfill? Leaking pressure hose? (there are two) Leaking resivoir to pump? Loose cap?
To find out witch it is,pump or rack and pinion,break loose the presure line on the power steering pump with a wench.Start the car and turn the steering wheel back and forth,you may need to loosen the nut on the power steering hose two or three turns to get the fluid to shoot out.It should come out pretty forceful.If it doesn`t,then replace the pump.If it does come out really powerful,replace the rack and pinion.
The only way I know of to bleed a power steering system is to turn the steering wheel from lock to lock (all the way to one side and then turn all the way to the other side) 3 or 4 times. that will bleed all the air out of the system. You might have had a leak for a longer than that you realized and by fixing the hose the power steering works VERY good and you are no long used to how easy it once worked.
