Stong possiblity of tire balance problem. If you live in a cold weather State as I do, you may have ice built up on the inside of the rim causing an imbalance. Front wheels are the likely focal point.
mine does it too, i attribute it to the fact that the vibrations of the engine just shake the whole car, seeing how the steering wheel isn't attached by much, it'll shake, kinda like the way your rear view mirror will shake with alot of bass, vIbRaTiOnS
Too much positive caster
it should be 5inches between a driver and steering wheel
well I've got my steering wheel out of an old car that's much more easy its hooking it up that's hard
About 5 bucks
You should sit comfortably holding the wheel with your arms slightly bent at the elbows. Do not sit close to, or 'crowd,' the steering wheel, or you may suffer injury when the bag deploys.
The 2010 Chevy Cobalt power steering wheel will cost you about $400.
Steering wheel size is pretty much standard and that is about it.
Power steering has a pump driven of the engine that pressurizes hydraulic fluid to assist in moving the steering rack. Manual steering doesn't have the pump, so the effect to turn the steering wheel is high, especially at low speeds. Manual steering racks have a higher gear ratio to make it easier but an example is to turn your steering wheel with the engine off. You can get an idea of how much the pump helps.
