If you mean "what" is making noise when you turn the steering wheel? It usaually means you need power steering fluid. If you run too long without power steering fluid it will make your power steering go out. If it is making a shuttering noise when you take sharp turns. Your rear differential may need to be serviced. I would have is burnished.
Usually it is a warning sign of your wheel bearing going bad.
When you turn the steering wheel and hear a popping noise, it could be due to the power steering pump and a sticking valve so there is not enough hydraulic pressure. It could be caused by the steering linkage going out or low power steering fluid.
It is very hard to turn the steering wheel and/or a whining or squealing noise when you turn the steering wheel.
