Steering will "wobble" at higher speeds and sometimes when braking. General looseness in steering.
You either have worn steering components like bad inner or outer tie rod ends, or worn lower ball joints. Sometimes a broken belt on a tire can cause shaking, but that's usually at lower speeds.
possibly your tires or a wheel bearing, listen at lower speeds, if you rock the steering wheel back and forth and it comes and goes it's probably a wheel bearing
Could be a minor out of balance condition with one of the tires, or a minor alignment issue that is unnoticeable at lower speeds. Also the tires may not be rated for the speeds you are attempting and are distorting. Another possibility is a harmonic imbalance, the tread of the tires may create a noise that causes a wobble in the steering, the sound is always there but raises to a harmful pitch at a certain speed.
yes,because engine will stop if engine will stop ,power steering pump will stop. Yes, the power steering pump is powered by the rotation of the motor which is powered by fuel. If the motor stops the pump stops and steering becomes very labored especially at lower speeds.
on most vehicals that kind of shaking is caused by a worn out steering component. steering dampner or idler arm.
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
when your going fast you hit harder which causes more damage, but when your going slow you hit slower than you hit fast which cause less damage.
its suspension performance will become low.
Biplanes have more lift at lower speeds.
There is usually a knob on the bottom of the steering column, you push forward or back to raise or lower the steering wheel.
