Why do Ford power steering pumps whine?

Why Ford Power Steering Pumps Whine
Ford power steering pumps can whine due to various reasons, including trapped air in the system, worn-out power steering fluid, or issues with the pump itself. Here are some common causes and potential solutions:
Trapped Air in the System:
– Air trapped in the power steering system can cause whining. Certain pumps may have difficulty allowing air to escape, leading to noise issues.
– One method to address this is to use vacuum to remove the trapped air. This can be done by using engine vacuum or a mityvac to purge the air from the system.
Worn-Out Power Steering Fluid:
– Worn-out power steering fluid that has lost its additives or physical properties may not pump well, leading to whining.
– Changing the power steering fluid and refilling it with fresh, clean fluid is recommended to address this issue.
Pump Issues:
– The power steering pump itself may be the source of the whining noise. Some users have reported success in reducing or eliminating the whine by replacing the Ford power steering pump with a Saginaw pump, which is known for being quieter.
– Using ATF fluid instead of power steering fluid may also help reduce the whining noise associated with the power steering pump.
In summary, the whining noise from Ford power steering pumps can be caused by trapped air in the system, worn-out power steering fluid, or issues with the pump itself. Addressing these issues, such as by purging air from the system, changing the power steering fluid, or considering a pump replacement, can help mitigate the whining.
