Leaking Power Steering Fluid — The power steering system uses a special fluid to transfer the pressure to change the direction of your wheels. If this fluid has been compromised and is leaking, then the ability to build pressure in the fluid is harder to do. This means that taking curves and turns can be near impossible. You can easily spot this because you will notice fluid dripping from the driver’s side. There is also a grinding noise that can be heard when taking turns. If you run out of fluid, you can burn out the power steering pump.
Cracked, Peeling or Worn out Hose — Every part of your vehicle wears out with time. The components of your car are under stress when driving and this can cause damage. After a few years, you will notice that the hoses associated with the power steering system have become hardened and begin to crack. Your hose is also located close to other parts and the tubes can become worn out. These can lead to holes or cracks in the hoses which will eventually leak out power steering fluid.
Loose Hose Couplings — Just as how your hoses can become damaged throughout normal use of your car, the couplings that connect your tubes together begin to get loose. This is caused by vibrations, sudden bumps or by the pressure of the system itself.
Slipped Drive Belt — The drive belt on the power steering pump slipping off is a common problem associated with power steering. This will completely prevent your car from changing direction as there is nothing to let the pump know what direction it should be applying pressure to. You can notice this easily when you hear a squealing sound when you turn the steering wheel into a sharp turn.
Worn Out Steering Pump — As your car gets older, so does the power steering pump. The seals and internal parts of the pump break down and lead to loss of fluid pressure. This can be diagnosed through loss of steering ease and through squealing sounds.
