Turning Effort Test

Turning Effort Test

NOTE: Make sure front wheels are correctly aligned and tire pressure is correct before checking turning effort.

1. Park the vehicle on dry concrete and set the parking brake.
2. Idle the engine for two to three minutes. Turn the steering wheel to the left and right several times to warm the fluid to 43 - 49°C (110 - 120°F).
3. With the engine running, attach a pull scale to the rim of the steering wheel. Measure pull required to turn one complete revolution in each direction. Refer to Specifications for Static Steering Wheel Turning Efforts for acceptable measurements.
