  1. Remove the nuts or bolts attaching the steering coupling clamp in the instrument panel support.
  2.  
  3. Lift the column out of the truck.
  4.  

To install:
  1. Position the column in the truck.
  2.  
  3. Connect the coupling flange with the coupling on the wormshaft. Don't tighten the nuts yet.
  4.  

Position the column so that the flange face is parallel with the coupling face. On 4-wheel drive models, position the column to center the steering shaft bearing blocks in the pot coupling.

  1. Install the 2 upper bracket bolts, but don't tighten them yet.
  2.  
  3. With the front wheels straight ahead, center the shaft in the shift tube. A centering tool such as C-4134 will help.
  4.  
  5. Install the support plate on the firewall. Tighten the bolts.
  6.  
  7. Slide the O-ring into position on the support plate and tighten the screws.

  10.  
  11. Remove the centering tool.
  12.  
  13. Connect the shift indicator pointer to the operating bracket in its original location. Slowly move the shift lever from L to P , pausing briefly at each position. The pointer must align with each selector position. If necessary, loosen the bolt and readjust the linkage to align the pointer correctly.
  14.  
  15. Connect the wiring to the column.
  16.  
  17. Install the steering wheel.
  18.
