After bleeding the power steering the pump may make a noise because there isn't enough power steering fluid in it.
Noise may be heard in a power steering line when the power steering fluid is low. Low power steering fluid may occur due to a leaking power steering pump in most cases. If the pump is not leaking, then the fluid needs to be added.
If your power steering pump makes a whining noise as you turn your steering wheel your power steering fluid reservoir is probably empty. The noise is caused when your power steering pump tries to pump fluid that is not there. This indicates that you probably have a leak somewhere in your power steering fluid lines. You can either try to find the leak or simply replace the power steering fluid every so often.
check your power steering fluid
power steering fluid not filled?
When their is air in the power steering hoses it will create noise. This is bad, as it can result in a dry pump which will eventually lead to pump failure.
Yes it does. Check your power steering fluid level.
Noise from am power steering pump can be caused by several things. The fluid could be low, the belt could be loose or the pump can be beginning to fail.
If you mean "what" is making noise when you turn the steering wheel? It usaually means you need power steering fluid. If you run too long without power steering fluid it will make your power steering go out. If it is making a shuttering noise when you take sharp turns. Your rear differential may need to be serviced. I would have is burnished.
check the power steering fluid level. I would have to say your low on fluid.
Loose power steering belt/worn power steering belt/defective belt tensioner.
Possibly a worn belt on the power steering pumo.
