Among the common symptoms of a bad power steering pump are whining noises that coincide with engine speed. The power steering pump is driven off the engine via a belt. If you have a bad pump, it could whine the moment you turn your engine on. Whining noises are often caused by a low fluid level or worn out pump.

The whine is usually created by a problem with the power steering fluid that the pump is trying to move. If you’ve kept up with regular maintenance on your car including changing your power steering fluid as recommended, then the whine is most likely due to air bubbles in your system.

Among the common broken power steering pump symptoms are whining noises that occur at the same time with engine speed. The power steering pump is operated by the engine via a belt. When you have a malfunctioning pump, it could whine or produce a growling sound the moment you kick-start your engine.

You either have excessive air in the fluid of the system that will gradually work its way out over a few days to a week, or the pump is defective. Look in the power steering reservoir and you will likely see the fluid has small air bubbles in it. This is cause of the noise.

AN fittings are fine for power steering and power brake (hydroboost) applications. Performance crowd has been using them for years.

Tractor supply hydraulic hose will work fine. Normal operating pressure is around 2500PSI with a burst rating about 5000PSI. All HP fittings should be crimped or Aeroquip.

Registered. The torque specification for a power steering metric o-ring fitting is 15 to 25 ft-lbs. The torque spec for the older style 45 degree flare fitting is 25 to 35 ft-lbs.

Smooth Bore PTFE hose offers low volumetric expansion at maximum operating pressure making it ideal for pressure systems such as brake, clutch, power steering, gearbox and suspension hydraulics. Low expansion provides a more positive brake pedal with less travel.
