I was trying to see the dials in my car today and didnt want to start the engine, so I just popped the key in to release the lock ont he steering wheel and turned it with the engine off. Obviously being power steering adn as the car was not moving, it was very difficult to turn, which got me wondering if its actually ok to do such a thing? Does it casue strain on any of the mechnical parts of the steering (i know its not good for the tyres) and could it casue damage to anything?
