Front Wheel Turning Angle

  1. Check toe-in. Refer to "WHEEL ALIGNMENT (UNLADEN*) ".
  2. Place front wheels on turning radius gauges and rear wheels on stands so that vehicle can be level. Check the maximum inner and outer wheel turning angles for LH and RH road wheels.

  3. Start engine and run at idle, turn steering wheel all the way right and left, measure the turning angle.

    Inner wheel (Angle: A) 

    • Minimum: 39°4' (39.75°) 
    • Nominal: 42°45' (42.75°) 
    • Maximum: 43°45' (43.75°) 

    Outer wheel (Angle: B) 

    • Nominal: 33°50' (33.83°) 
  4. Check the following items when turning angle is out of the standard.
    1. Check rack stroke.

      Rack stroke "L" 

      Except for RAS models: 68.5 mm (2.697 in) 

      RAS models: 66.0 mm (2.598 in) 

    2. Disassemble steering gear assembly to check the cause that rack stroke is outside of the standard. Refer to "DISASSEMBLY AND ASSEMBLY ".
    3. Steering angles are not adjustable. Check steering gear assembly, steering column assembly and front suspension components for wear or damage if any of the turning angles are different from the specified value. Replace any of them, if any non-standard condition exists.
