Some vehicle may exhibit a knocking noise from the steering column while driving. This may be caused by a gap between the intermediate shaft (upper side) and the joint bolt. To eliminate this concern, the intermediate shaft and the joint bolts have been modified to reduce backlash.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
