Fig. Fig. 2: Steering wheel alignment and installation

  1. Remove the steering wheel-to-steering shaft retainer clip (snapring), then loosen and remove the nut.
  2.  

Since the steering column is designed to collapse upon impact, NEVER hammer on it!

  1. Matchmark the relationship of the steering wheel to the steering shaft. Some models may already be equipped with one or more alignment marks. If not, make your own using a permanent marker.
  2.  
  3. Using a suitable steering wheel puller, such as No. J-1859-03 or equivalent, carefully draw the wheel from the steering column.
  4.  

To install:

Before installing the steering wheel, be sure that the turn signal switch is in the Neutral position. DO NOT mis-align the steering wheel more than 0.8 in. (20mm) from the horizontal centerline.

  1. Align the matchmarks and carefully fit the wheel onto the steering shaft splines.
  2.  
  3. Install the retaining nut and tighten to 30 ft. lbs. (40 Nm).
  4.  
  5. If equipped, install the horn pad.
  6.  
  7. Connect the negative battery cable.
