Official summary
Some vehicles may exhibit a light resistance and/or an unusual noise when turning the steering wheel in either direction. This concern may be caused by insufficient lubrication between the worm wheel gear and worm shaft. To eliminate this concern, the amount of grease between the worm wheel gear and worm shaft was increased and the housing end cover shape was modified.
Vehicles covered
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.
