how can you tell if you need a new power steering pump , been told by someone mine might need changing when you turn in to a nearside bend and accelerate there is a vibrating and a funny noise as well , doesnt matter if you accelerate slow or hard the vibrating is there if you just turn in normally its ok

 

cv joint

 

dont think its the cv joint as the vibrating is felt thru the steering wheel and its more of a buzzing noise

 

try changing the fluid. surely if it wee pump related you would have the problem in either turning direction.

 

my My steering pump went in my 01wrx after performing doughnuts on some grass and then a trip to le mans in the heat killed it off. The steering in it just died, returned to manual basically. Sounds more like tracking or something to me, wheel alignment maybe?

 

When my pump went No power assist at idle but there was when moving at higher revs. It does sound like alignment.

 

If you are describing a vibration through the steering which is present when turning the wheel even when stationary,then it could be a steering rack problem.

Check/change pas fluid and keep fingers crossed.
