Power Assist Check
Check
1. Start the engine, let it idle.
2. 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.
3. If the scale reads no more than 34 N (3.5 kgf, 7.7 lbs.), the power assist is OK. If it reads more, check the steering linkage for damage, and check the rack guide adjustment.
