Check the axle; it may be leaking/out of grease.
I would suspect a CV joint is bad.
Power Steering Fluid Or Power Steering Pump
It probably needs steering fluid.
try checking fluid level
It could be low on power steering fluid. That is a common problem. It makes a sharp whining noise when you turn the steering wheel.
An expert would have to hear the noise. Some possibilities are dry top bearing of the shocks, horn ring loose in steering wheel, tire rubbing on frame - -
you power steering belt is in need of replacement of the pump is bad if you have done that
If a car makes noise when turning the tie rod can be worn. Tie rods allow a vehicle to turn, when they fail the steering wheel will knock and rattle making all kinds of noises.
If the sound is a loud growling , whining, noise you're probably low on power steering fluid. Now the cause of the fluids loss is WHERE ?
something hitting the pipe, hot water pipe touching cold water pipe, or is it burping noise ? a tapping noise is sharp, do you live in an apartment ? is this a house, lot s of causes,
hydraulic lifter? Rocker arm?
Might be due to low/no fluid level in the power steering reservoir.
