Power Steering Noise

[DaveM]

My 98 2.8V6 has developed a loud hum and slight vibration when I turn the steerng wheel.

 

The power steering seems un-effected, i.e. it still works, it's just very noisy

 

Any ideas what it is, (belt vibration of some sort?)

and how much is it likely to cost to get fixed ?

 

thanks all

I assume the oil level is ok, get some one to turn the steering while you look around to trace the noise,

as long as the level is ok it would have to be from the pump, power steering works on the principle that

oil is going around the system continually, when you turn the steering some of the pressure is diverted

to assist the rack movement, make sure all steering pipes are secure and cannot vibrate,
