Condition
Some customers may comment on a clunk or knock noise being heard or felt through the steering wheel and/or brake and accelerator pedals. This issue may be more prevalent in hotter temperatures.
Cause
This condition may be caused by a slip/stick condition in the lower steering (intermediate) shaft.
Correction
Important:
When replacing the lower intermediate shaft, follow service procedures found in published Service Information (SI). 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 its straight position prior to removing the lower I-shaft. Keep the steering column 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 or green mark as identified in the graphic.
