Steering Power Assist Check

1. NOTE: This test should be done with original equipment tyres and wheels at the correct tyre pressure. For the hydraulic power steering type, check the power steering fluid level. 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 (hydraulic power steering type). 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 tyres begin to turn. If the scale reads no more than specifications, the gearbox and pump are OK. For the hydraulic power steering type, if the scale reads more than specifications, troubleshoot the steering system. For the EPS type, if the scale reads more than specifications, check for steering linkage, and check the rack guide adjustment.
