Air in Power Steering Symptoms.

Trapped air in a power steering system is a very common issue. The symptoms are normally very obvious, and most people who have a driven a vehicle with a traditional hydraulic power steering system have experienced the moan or whine that indicates the air being pushed through the system by the power steering pump. This noise will often be overlooked initially because it will not contain any other issues other than just a noise coming from the engine compartment. But left alone and not repaired, eventually this air will cause further damage to the power steering system.

Signs Your Power Steering is Going Bad.

There are a number of different signs that your power steering system is developing issues. Most people have heard a key sound that becomes present when your power steering system has developed an issue, and that is a moaning sound under coming from under the hood when the steering wheel is turned side to side. That noise is the most telling sign of a power steering system that is failing. The reason for the noise is normally due to air being in the system and the hydraulic power steering pump cavitating, causing a mixture of both air and fluid to be pushed through the power steering system.

Signs you Need to Change Power Steering Fluid.

There are a number of different signs you need to change the power steering fluid in your vehicle. Just like any fluid in your vehicle, the power steering fluid has a lifespan. With all vehicle fluid lifespans, you should always start by checking for OEM recommendations. These recommendations can often be found in the vehicle's owner's manual.
