Tech Tip: Hyundai Power Steering Pump Whining Noise

Before replacing a power steering oil pump on a 2003 Accent for a "whining" noise condition, check the oil pump reservoir filter screen for contamination. If the filter screen at the bottom of the oil pump reservoir is clogged, it may cause the pump to aerate and produce a "whining" noise.

If the filter screen is clogged, replace the reservoir and reconfirm the condition. Fig. 1 shows the location of the screen in the reservoir.

Note: For proper inspection of the screen, it may be necessary to empty the power steering oil pump reservoir.
