# Service bulletin 9100841 Rev 1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 11034380
- Published by NHTSA: 2026\-07\-02
- Manufacturer's number: 9100841 Rev 1
- Manufacturer's date: 2026\-06\-25
- NHTSA component: POWER TRAIN

## NHTSA's summary

If customer concern diagnosis leads to suspect u\-joint issue with the prop shaft, u\-joint service kit should be utilized to fix concern. Prop shaft replacement would not be required.
