Power Assist Check
Power Assist Check
NOTE: This test should be done with original equipment tires and wheels at the correct tire pressure.
1. Hydraulic power steering type: Check the power steering fluid level.
2. Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the component and the fluid (power steering type).
3. Attach a commercially available spring scale to the steering wheel. With the engine idling and the vehicle on a clean, dry floor, pull the scale as shown, and read it as soon as the tires begin to turn.
- If the scale reads no more than the specification, the steering gearbox and pump (power steering type) are OK.
- Hydraulic power steering type: If the scale reads more than specifications, troubleshoot the steering system
- EPS type: If the scale reads more than specifications, check for steering linkage, Steering Linkage and Gearbox Inspection and check the rack guide adjustment. Adjustments
