Inspection (All Steering Columns): Notes

  1. Check for separation of the 2 break-away capsules. If capsules have moved more than 1/16" (1.6 mm), some column collapse may have occurred. Check for damaged steering shaft components.
  2. Inspect jacket section of column for looseness, bends, collapsed mesh or bellows section. Check for mast jacket collapse by measuring for proper dimensions. See Fig 1 .
  3. On column shift models, check operation of shift lever. If lever can be moved to "PARK" position without raising lever, upper shift tube plastic bearing is broken.
  4. Inspect intermediate and steering column shafts for sheared plastic pins. If the shafts rattle when tapped lightly from side, pins are sheared. Replace any collapsed or damaged parts.
