Steering Shaft Coupler: Testing and Inspection
LOWER STEERING COLUMN COUPLINGThe steering column lower coupling and its flexible (universal) joint must be inspected whenever any of the following conditions exist:
- After the vehicle has been involved in a collision which deploys the airbag, regardless of the extent of damage to the vehicle.
- After the vehicle has been involved in an undercarriage impact which results in any type of damage or bending of front suspension components or the frame of the vehicle.
- Under any conditions which result in the steering gear, steering column or steering column shaft receiving a force great enough to move the steering column or shaft forward or rearward in the vehicle.
Inspect the lower coupling shaft and its flexible joint for any of the following conditions:
- Seized or binding universal joint
- Loose bearing stakes
- Bearings not fully seated
- Shaft bent
- Collapsible shaft binding
Upon inspection, if any of the above conditions exist, replacement of the entire steering column lower coupling is necessary.
The collapsible portion of the lower coupling intermediate shaft should easily slide back and forth between fully collapsed and fully extended positions. The force to move the shaft should not exceed 50 lbs. (23 Kg) of force. If found to exceed, replace the steering column lower coupling.
