If effort is not given to steering wheel, front wheels also would not turn. When a turn is taken, no such effort is given to rear wheels for turning because the cars are usually front wheeled steered. So it is the inertia of the wheels and the car which causes the rear end of the car not want to turn when turning and they usually slip.
The cause of the squealing sound is because you are turning the steering wheel completely to the right or left
the car may be low on power steering fluid
Notchy feel when turning the steering wheel Noise from the pump area when wheels are turned Possible stiffness when turning steering wheel.
The rotation of the steering shaft drives the turning of the wheels, and buses and large trucks have wheels which are significantly more massive than cars' and light trucks', requiring more torque on the steering shaft to turn the wheels. The larger steering wheel gives a mechanical advantage in turning the steering shaft; a longer moment-arm from the application of force by the driver on the steering wheel results in a larger torque on the steering shaft from the same force applied.
weak power steering pump, or worn rack and pinion. 65;
Two reason why your steering wheel is not turning.One....your ignition key is removed and you have turned the steering wheel to LOCK position.Two your front wheels are pinned against an obstacle so your front wheels are blocked.
the steering wheel wont make the front wheels make noise as there is no generating source from the steering wheel. it will be the other way around.
Assuming you mean the steering column, it is what transmits the turning of the wheel in your hands to the steering mechanism which moves the wheels that are touching the ground.
The purpose of the steering system allows the driver to control the direction of the vehicle by turning the front wheels.
Wheels are out of balance
