When the car is driven at low speed, the Power Steering gives full assist so the driver can
turn the steering wheel easily. Parking or turning tight corners can be done with little effort.
As vehicle speed increases, the mount of power steering assist is reduced and the steering wheel becomes harder to turn. This gives the driver more feedback about road conditions through the steering wheel and better vehicle control. If an emergency arises and the driver needs to turn the steering wheel quickly, the full power assist is provided almost immediately after the wheel is turned only a few degrees.

Why on your 1999 ford expedition the steering is over sensitive y?
It's call Power Steering.
Is electronic power steering better than the hydraulic power steering?
Hydraulic power steering is a primitive technology used for decades and has improved a lot with time. Earlier, it did not have any difference in steering response with speed of the car, but the new age of hydraulic power steering are speed sensitive and work better than the older hydraulic power steering.Electric power steering are comparatively new technology with less complicated build and mechanism, takes less space and are more durable. Electric power steering use sensors to sense the car speed and will take care of the different steering response required for different speeds.Some of the main differences are as below:1. Hydraulic Power Steering System is complicated compared with Electric Power Steering2. Hydraulic Power Steering System usually weighs more than Electric Power Steering3. Hydraulic Power Steering uses hydraulic fluids for operation whereas there is no such fluid needed for Electric Power Steering, thus Electric Power Steering needs less maintenance compared to hydraulic power steering.4. Electric Power Steering gives better response at different speeds as compared to Hydraulic Power Steering5. Eclectic Power Steering is less prone to problems and faults and are more durable as compared to Hydraulic power steering.6. Hydraulic power steering extracts power from engine, so it reduces the fuel mileage of the engine. Electric power steering consumes power from battery which is also charged by engine, but it consumes less power compared to Hydraulic power steering. So a car having Electric power steering will give more mileage than one with Hydraulic power steering.Conclusion :Electric Power Steering is better than Hydraulic Power steering.Hope this helps :-)
Why is my grand marquis power steering is too sensitive at speed?
I have no experience of the make of car to which you refer but the same rules should apply. Power steering designed to assist in tight parking is dangerous at speed. The system should have a feature whereby the higher the revs. the less assistance from the power steering pump. If not you could be driving North on the Free-way,suddenly you sneeze, 2 seconds later you are creating carnage in the South bound lanes. I urge you to take your car to a specialist.
Which correctly describes speed sensitive variable assist steering?
Increases assist at highway speeds to increase maneuverability
What are the car specs for the Opel Corsa SXI?
The car specifications for the Opel Corsa SXI include that one can get it as a manual or automatic transmission, it has five seats, speed sensitive power steering, and many other features.
Why does 2001 Chevy Tahoe steering sometimes gets hard to turn to both sides and gets easy when accelerate?
The power steering output is directly proportional to the engine speed [RPM]. I suspect that when it is difficult to turn, the engine is at idle speed, which is set too at too low an RPM. Then when you depress the accelerator, the engine speed increases and the power steering pump speed and output power increase also. Have a qualified mechanic check and properly set the engine idle speed to the manufacturer's specifications. IF the idle speed is not abnormally low, would suggest a badly worn power steering pump. Properly set idle speed first, and if that does not correct the problem, then have the power steering pump output checked.
Can the power of the power steering be reduced in a 2006 Buick Lacrosse?
According to the TSM for the lacrosse there is a sensor that will increase the power steering at low speeds to have greater steering capability. When it increases in speed the power steering lets off to make the wheel "tighter" feeling. If you are looking to get it "reduced" there is probably an issue with the sensor or the power steering system. cheapcurrent.com
What is a gem module on a Mercury Sable?
It controls the variable power steering on your vehicle. The faster the car goes the less power steering the vehicle needs. The module is what controls that. It senses the cars speed and then determines how much power steering "power" needs to be applied.
Will a gear box from a 1968 Chevy truck work in 1967 Chevy truck?
Need more info, manual steering gear box, power steering gear box, 3 speed standard transmission box, or 4 speed transmission box? The truck has a 3 speed manual transmission and power steering gear box thanks The steering gear box will interchange.
What viscosity is power steering oil?
The viscosity of power steering fluid is not relevant to it's job (within reason) but more it's ability to function under extremely harsh and high pressure conditions. All these fluids are merely hydraulic oils as is ATF with Honda fluid containing an additional lubricant additive needed for their speed sensitive steering gears. Use exactly what the manufacture of your vehicle recommends and nothing else.
What causes your steering wheel to become hard to turn?
A few things could cause this. Low power steering fluid, too slow engine speed (low RPMs), faulty power steering pump or broken power steering pump belt, binding or poorly lubricated steering linkages, faulty steering gear, etc.
How do you tell if your power steering is bad?
How would you know if your power steering pump was bad on a 1992 Lexus ls 400?Any of the following symptoms can indicate a faulty power steering pump:Lack of steering assist (i.e. steering wheel difficult to turn, especially at low speeds)A whining sound that becomes higher in pitch as engine speed (not vehicle speed) increasesA thin, oily fluid leaking from the engine compartment onto the ground below, accompanied by a drop in the power steering fluid reservoir level
