my impreza makes a strange noise, like a whining noise just as its warming up and there after, when you turn left or right etc it sounds as though the power steering pump is broken, as it gets louder and aswell when the car is revved which seems to ring true as the belt will be turning faster.

Just wondering how easy it is to change the pump on a MY99 classic STI??

Are you sure it's not a loose belt ?

 

would that make a horrible whining noise?

 

Have you checked the fluid level mate?

 

Will check belt and fluid, is it just normal power steering fluid that they use?

 

Yes its just standard power steering fluid mate

 

I always thought that the Subaru pumps use ATF (automatic transmission oil) tbh.
At least my GC says so on the plastic cap.

 

as above get ATF it should say the spec on the lid...

also mine has been making odd noises & a droning whining noise, new Gates belts on yesterday & hey presto sweet as a nut
