Hi,
I have had a noisy power steering pump for some time now.
The noise is like a loose bearing which changes when the steering is moved or the engine is put on load.
I replaced the belt and the pulleys just to make sure it was the pump, as this was a cheaper option. But the whyning was still happening. I purchased a new pump the other day and replaced it. Refilled the header tank and started the engine. Then put the steering from lock to lock to try to bleed the system.
But the whyning is still there. I have checked the pipes going to the rack and they appear ok, no kinks. Another issue is that the fluid is now very airrated.
Could there be issues with the rack?
Can anyone shed any light on this?
Thanks
