1. The lower column bearing housing assembly (1) may be out of position. The 1st picture shows the lower column bearing assembly (1) in its correct
position, while the 2nd picture below shows the lower column bearing out of position.
2. The upper intermediate steering shaft to lower column shaft bolt and nut (2) may be contacting the inhibitor/shiftier cable bracket, as shown below.
Recommendation/Instructions
Note: Do NOT replace the steering column for these conditions
Important: To correct either above condition, repair the steering column assembly by replacing the column lower bearing adapter assembly and retainer as instructed in the following. Below are the highlighted steps for the repair, but please refer to SI “Steering Shaft Lower Bearing Adapter Replacement” for the complete procedure and torque specifications.
