Turning Effort Test

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Make sure the front wheels are correctly aligned and the tire pressure is correct before checking the steering effort.
  1. Park the vehicle on dry concrete and set the parking brake.
  2. Insert a thermometer into the power steering oil reservoir.
    3. CAUTION: Do not hold the steering wheel against the stops for more than 3 to 5 seconds at a time. Damage to the power steering pump can occur.
  3. Idle the engine for 2 to 3 minutes. Turn the steering wheel from stop-to-stop several times to warm the fluid to 50-60°C (122-140°F).
  4. With the engine running, attach the spring scale to the rim of the steering wheel.
  5. Measure the pull required to turn the steering wheel one complete revolution in each direction. Refer to TURNING EFFORT TEST .
