Steering Gear Grunt/Shudder Test
WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
- Start and run the vehicle to operating temperature.
- Set engine idle speed to 1200 RPM.
- Rotate the steering wheel to the RH stop, then turn the steering wheel 90 degrees back from that position. Turn the steering wheel slowly in a 15 degrees to 30 degrees arc.
- Turn the steering wheel another 90 degrees. Turn the steering wheel slowly in a 15 degrees to 30 degrees arc.
- Repeat the test with power steering fluid at different temperatures.
- If a light grunt is heard or a low (50-200 Hz) shudder is present, this is a normal steering system condition.
- If a loud grunt is heard, or a strong shudder is felt, fill and purge the power steering system.
CAUTION:
Do not hold the steering wheel against the stops for more than three to five seconds at a time. Damage to the power steering pump will occur.
