Official summary
The Wrench - When performing the Service Bulletin GL1800 #1- Loose Handlebar Repair on 2018 GL 1800, or removing the Steering Bridge to adjust the upper steering stem nut on any 2018 and newer GL1800, the left rear tie rod bolt needs to be held by a 14 mm open wrench to prevent the bolt from turning when loosening the 17 mm upper nut. If the bolt is not supported, the rubber bushing will be damaged, which will then need to be replaced. Bushing damage will not be covered by warranty.
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.
