- The problem
- The intermediate shaft coupling on the involved vehicles may have been machined oversized in the serration area where it attaches to the steering column. This would prevent the coupling from properly tightening on the shaft when the clamp and pinch bolt were installed.
- The fix
- Dealer will replace the shaft coupling, if necessary, without charge to owner.
