Truck started making awful noise suddenly. Kind of like ball joint grinding but much louder.Only when making a turn. Looked under hood and the two hoses going from pump to up behind brake master cylinder pulses badly when turning wheel and you can feel the pulsing in the steering wheel..
Fluid and belt are fine, any suggestions ?
thanks for any help.

 

check your power steering fluid level first. your hose could be bad or it could be the p/s pump. is any fluid leaking?

 

Fluid level is fine, hoses look practically new and no leaks and have never added any fluid.
