Fig. Fig. 3: Adjusting the torsion bars with a spirit level

  1. Disconnect the shock absorber at the axle.
  2.  
  3. Place a jack under the frame and lift the truck until the front wheel hangs freely.
  4.  
  5. Back off on the torsion bar adjusting screw, located in the frame rail at the rear of the bar, until the end of the screw is flush with the inside of the frame rail.
  6.  
  7. Remove the two locknuts, washers and bolts attaching the torsion bar anchor support bracket to the frame side rail.
  8.  
  9. Slide the anchor support bracket, adjusting arm and torsion bar to the rear to remove them from the truck. The split rubber grommet at the front end of the torsion bar will come off with the bar. On late model trucks, the grommet is omitted.
  10.  

The left and right torsion bars are not interchangeable. They are stamped with the letter L or R for identification purposes.

  1. With the axle hanging freely, insert the hex end of the new torsion bar in the hex tube.
  2.  
  3. With the torsion bar in its normal position (parallel to the frame rail), and with the lower end of the adjusting arm in contact with the side rail, slide the adjusting arm onto the torsion bar. Mark the end of the torsion bar and the adjusting arm to indicate the relative positions of the serrations in each part.
  4.  
  5. Remove the adjusting arm from the torsion bar.
  6.  
  7. With a wood wedge, pry the torsion bar away from the side rail. Pry the torsion bar until there is a difference of two serrations (as indicated by the mark in Step 7,) when the adjusting arm is installed on the torsion bar with the lower end of the arm in contact with the side rail.
  8.  
  9. With the wood wedge in place, assemble the anchor support bracket and adjusting arm on the end of the torsion bar with the lower end of the arm in contact with the side rail.
  10.  
  11. Remove the wood wedge. Bolt the anchor support bracket to the frame side rail. Torque the nuts to 45-50 ft. lb. Turn in the adjusting bolt until it contacts the adjusting arm.
  12.  
  13. Remove the jack from the axle. Connect the shock absorber.
  14.  
  15. Level the axle with the torsion bar adjusting screw.
  16.  
  17. Tighten the adjusting screw locknut.
  18.  

If the full travel of the adjusting screw will not provide a level axle, repeat Steps 10 through 14 while increasing the specified difference of two serrations by one serration at a time until a level axle can be obtained with the adjusting screw.
