This can cause premature wear on the differential pinion head and tail carrier bearings, resulting in unacceptable differential noise and driveline vibration. *pe

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.
