Power Assist Check
Check1. 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 fluid.
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 and read it as soon as the tires begin to turn.
^ If the scale reads no more than specifications, the gearbox and pump are OK.
^ If the scale reads more than specifications, troubleshoot the steering system.
