ADJUSTMENTS



Steering gear adjustments are made only as corrections and NOT as periodic adjustments. Before adjusting the gear, check the remainder of the steering linkage and front suspension for wear or damage and repair/replace components, as necessary. Adjustment takes place in 2 major steps. First the worm bearing preload adjustment is made using the adjuster plug, then the overcenter preload is adjusted using the adjuster screw/bolt and jam nut.

  1. Position the front wheels in a straight ahead position.
  2.  
  3. Loosen the locknut on the adjusting screw of the steering gear unit.
  4.  
  5. Turn the adjusting screw clockwise to decrease the free-play or counterclockwise to increase it.
  6.  
  7. When the steering wheel free-play is between 0.39-1.17 in. (10-30mm), tighten the locknut to 1522 ft. lbs. (2029 Nm).
