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.
