Condition:

This condition may be caused by a slip/stick condition in the lower steering (intermediate) shaft.

Service Procedure
IMPORTANT:
When replacing the lower intermediate shaft, follow service procedures found in the Service Manual. Be sure to ALWAYS:
^ Keep the hub straight when removing/attaching the lower I-shaft to the upper steering column.
^ Pin the steering column using the J 42640 - Steering Column Locking Pin in it's straight position prior to removing the lower I-shaft. Keep it pinned until after the new lower I-shaft is installed.
Failure to perform these steps could result in a mis-alignment of the upper steering column to the lower I-shaft and cause DTC C0710 and "Serv Stab System" message to occur.
Replace the lower steering (intermediate) shaft. The new I-shaft can be identified by a yellow mark as identified in the graphic.
