Removal & Installation



  1. Disconnect the steering shaft from the gear.
  2.  
  3. Raise and support the truck on jackstands.
  4.  
  5. Disconnect the center link from the pitman arm.
  6.  
  7. Remove the front stabilizer bar.
  8.  
  9. Remove the pitman arm nut. Matchmark the arm and shaft, and remove the arm with a puller.
  10.  
  11. Unbolt and remove the gear.
  12.  
  13. Installation is the reverse of removal. The pitman arm nut MUST be securely staked. Observe the following torque specifications:

    Steering gear-to-frame: 65 ft. lbs. (88 Nm)
     
    Pitman arm-to-shaft: 185 ft. lbs. (250 Nm)
     
    Stabilizer bar-to-frame: 55 ft. lbs. (75 Nm)
     
    Stabilizer bar-to-link: 27 ft. lbs. (37 Nm)
     
    Center link-to-pitman arm: 55 ft. lbs. (75 Nm)

ADJUSTMENT




WARNING
Adjust the wormshaft bearing preload and pitman shaft overcenter drag torque in the order listed below. Failure to follow the procedures exactly may result in gear failure.

  1. Raise and support the vehicle safely.
  2.  
  3. Check the steering gear mounting bolt torque. It should be 65 ft. lbs. (88 Nm).
  4.  
  5. Matchmark the pitman arm and shaft, and remove the pitman arm nut. Remove the arm with a puller.
  6.  
  7. Loosen the pitman adjusting screw locknut, then back off the adjusting screw 2-3 turns.
  8.  
  9. Remove the horn button and cover. Slowly turn the steering wheel in one direction as far as it will go, then back 1 / 2 turn.
  10.  
  11. Install a socket and inch-pound torque wrench on the steering wheel nut. Measure the worm bearing preload by turning the wheel through a 90° arc ( 1 / 4 turn) with the wrench. Preload should be 5-8 inch lbs.
  12.  
  13. If preload is not within specifications, turn the adjuster screw clockwise to increase, or counterclockwise to decrease, the preload.
  14.  
  15. When the desired preload is attained, tighten the adjuster locknut to 50 ft. lbs. (68 Nm) and recheck the adjustment.
  16.  
  17. Rotate the steering wheel slowly from lock-to-lock, counting the number of turns. Turn the wheel back, 1 / 2 the number of turns to center the gear, then turn the wheel 1 / 2 turn off center.
  18.  
  19. Install the inch-pound torque wrench and socket on the steering wheel nut. Measure the torque required to tun the gear through the center point of travel. The drag should equal the worm bearing preload torque plus 4-10 inch lbs., but not exceed a total of 18 inch lbs.
  20.  
  21. If adjustment is required, loosen the pitman shaft screw locknut and turn the adjusting screw to obtain the desired torque. Tighten the locknut to 25 ft. lbs. (34 Nm) and recheck the overcenter drag.
  22.  
  23. Install all parts and check steering wheel alignment.
  24.
