air in fluid, insufficient fluid, leaky rack, plugged filter/strainer (if present) excessive effort required (at steering stop or wheel blocked), defective pump (internal seals), slipping belt, defective belt, defective pulley, defective belt tensioner are the first few that come to mind, other steering rack noises unrelated to Power Steering are also possible.
After bleeding the power steering the pump may make a noise because there isn't enough power steering fluid in it.
check the power steering fluid level. I would have to say your low on fluid.
Check the fluid in the power steering. If it is low the car will make noise when you turn the wheel.
check your power steering fluid
power steering fluid not filled?
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.
Yes it does. Check your power steering fluid level.
Power steering belt?
There could be a problem in the steering linkage but most likely, the power steering pump is bad or low in fluid
Check your steering pump to see if you need to add more power steering fluid.
Typically if your power steering fluid is low your car will make noise when you turn the wheel. If this is that case, I suggest taking your vehicle to an auto shop and have them do a power steering fluid check.
It is likely to be the power steering pump complaining that the power steering fluid is low.
