What if the X5 doesnt have Power Steering?
 

I know this is very random.. The Steering in the X5 is pretty stiff already, just can't imagine what will happened if there was no power steering.. anyone ever thought about that?

it's stiff in earlier model years, the later ones have servotronic much lighter steering, but at the same time not the same road feel

Check your steering fuild and leaks under your car.
