Engine running ask someone to turn steering wheel for you . Look for power steering hose move like there is pressure. and noise from power steering pump . if not change power steering pump
You don't really need power assistance when moving on the road ... where you need it more specially in parking or not really moving
hope it helps
Variable-assist power steering: A power steering system that uses valves and speed sensors to vary the amount of steering assist according to engine or road speed. At slow speeds more steering assist is delivered and steering the wheels is easier; necessary for parking, etc.. At higher speeds, steering assist is reduced and more steering effort is required to steer the car, giving the driver greater feel of the road. Also known as Speed-sensitive power steering.
Loss of current to the magnetic coils would cause a loss of power assist at low speed. Coil resistance can be checked with an ohmmeter, and should read about two ohms. An infinite (open) reading indicates a bad coil (requires replacing the rack since the coils are not serviceable). Checking for shorts between both sides of the coil assembly and rack housing is also recommended.
Hello i can assist you.Withe engine running remove your power steering reservoir cap and see if your power steering fluid is swirling if not it will be your power steering rack has failed internally and will need to be replaced.
The PS system probably has air bubbles in it. The air needs to be bled from the PS hoses and cylinders. You will also find it easier if you turn OFF the A/C when you are parking.
In a safe place (your driveway), Put gear in Park, set parking brake, replenish the power steering reservoir with fluid (not transmission fluid) and start engine. "Work" the steering wheel full counter-clockwise / full clockwise a few times. The "groans" you hear are voids of air travelling / escaping through the system. After it has quieted down, turn off engine, replenish fluid and do once more before test driving. Be sure to replenish fluid before testing / parking.
quite often ford steering pumps make noise, but if it is hard to steer, the fluid is probably low. First check underneath to see if there is a puddle, if there is then find and fix the leak. next, start it and get it to normal op. temp., while idling, pull the pump plug/ dipstick, check the level, add fluid if necessary. Steer the wheels back and forth a time or two, then check the level again. Double check underneath, visually inspect for puddles/wet spots. does the problem change after these steps? Theres not likely any water in it, therefore freezing isn't likely. Hope this helps.
Sounds to me like your power steering pump has gone bad. Being a vehicle with a hydro-boost brake system that would explain the power brake failure. Hydro-boost brake systems utilize pressurized power steering fluid to provide brake assist. In most lighter GVWR vehicles this function is performed by engine vacuum. There is a recall on certain Silverados and Sierras that addresses a faulty check ball in the booster, but your vehicle is affected by a steering issue as well. This would indicate to me that it is the pump. You can however check online to verify if your vehicle is affected by the recall. Hope this helps.
It is possible that the pump is failing...even though it is quiet. It could also be that the steering rack inner seals have lost their effectiveness. When the fluid heats up, it gets thinner, and it is more likely to leak past worn seals, which you undoubted have somewhere. But after 300,000 miles...you can't complain to GM. Those cars are about as bullet proof as they come. Good luck.
