What happens when there is air in the power steering system?

The power steering pump operates by hydraulics, and anything that operates by hydraulics can easily be affected if air gets into the system. Any air that gets into the power-steering system will be compressed by the pump and will result in noise and difficulty steering.

What are the symptoms of air in the power steering system?

A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
