* Power steering fluid level is low. If the power steering fluid level is low, the pump will have to work harder to circulate the fluid, which can cause noise. Check the power steering fluid level and add more if necessary.
* Air in the power steering system. Air in the power steering system can also cause noise. This can happen if the system has been recently repaired or if there is a leak. If you think there might be air in the system, you can bleed the power steering system.
* Worn power steering pump. A worn power steering pump can also cause noise. If the pump is worn, it will not be able to circulate the fluid properly, which can cause cavitation and noise. If you think the power steering pump is worn, you will need to have it replaced.
* Worn steering rack. A worn steering rack can also cause noise. If the steering rack is worn, it will not be able to move the wheels smoothly, which can cause friction and noise. If you think the steering rack is worn, you will need to have it replaced.
* Loose or damaged steering components. Loose or damaged steering components can also cause noise. This can include loose bolts, nuts, or ball joints. If you think there are loose or damaged steering components, you will need to have them tightened or replaced.
If you are not sure what is causing the noise when you turn your steering wheel, you should take your car to a mechanic for diagnosis.
