Power Steering Oil Pump Whine Noise - All Models
When replacing a power steering oil pump or inspecting a vehicle for a customer concern with
power steering whine noise, inspect the filter screen in the power steering reservoir for
contamination. If the filter screen has debris the fluid will be restricted from supplying the power
steering pump[ and may cause the fluid to aerate and cause a whine noise.
If debris or dirt is found in the reservoir filter screen, the reservoir should be replaced.
Tech TIP: It may be necessary to empty the power steering reservoir to properly inspect the filter
screen for contamination.
