Checking Procedure

    NOTICE: Vehicles involved in accidents resulting in frame damage, major body or sheet metal damage, or where the steering column has been impacted, may also have a damaged or a misaligned steering column.


    Object Number: 30561  Size: SH
  1. Check the capsules on the steering column bracket assembly. All the capsules must be securely seated in the bracket slots.
  2. Check for any loose conditions when the capsules are pushed or pulled by hand. If there are any loose conditions, the bracket should be replaced if it is bolted to the jacket assembly. If the bracket is welded to a jacket, replace the jacket assembly.

  3. Object Number: 30572  Size: SH
  4. Check the jacket assembly for collapse by measuring the distance from the lower edge of the upper jacket to a defined point on the lower jacket. If the measured dimensions are not within 65.53 ± 0.50 mm (2.56 ± .02 in), a new jacket must be installed.

  5. Object Number: 30567  Size: SH
  6. Visually inspect the shift tube for sheared injected plastic. If the shift tube shows sheared plastic, a new shift tube must be installed.
  7. Check the operation of the shift lever. The upper shift tube plastic bearing is broken if you can move the lever to the P (Park) position without raising the lever.

  8. Object Number: 30569  Size: SH
  9. Visually inspect the steering shaft for sheared injected plastic. If the steering shaft shows sheared plastic, a new steering shaft must be installed.
  10. Any frame damage that could cause a bent steering shaft must have the steering shaft runout checked.
  11. Use a dial indicator at the lower end of the steering shaft. Rotate the steering wheel. The runout must not exceed 1.59 mm (0.063 in).
