Power Assist Check
NOTE:
This test should be done with original equipment tires and wheels at the correct tire pressure.
- Check the power steering fluid level (see FLUID REPLACEMENT ).
- Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid.
- 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 in Fig 1 and read it as soon as the tires begin to turn.
- If the scale reads no more than the specification, the gearbox and pump are OK.
- If the scale reads more than the specification, troubleshoot the steering system (see SYMPTOM TROUBLESHOOTING ).
