# Service bulletin SBW35\-018

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.

- NHTSA id: 10184788

## NHTSA's summary

Western Star Service Bulletin for Axle Flange Gasket Replaced with O\-Ring. Daimler Trucks North America has released a new axle shaft to hub rubber O\-ring \(part number 11\-30728\-000\) as a replacement for the paper gasket \(part number 11\-14418\-000\). The new O\-ring will provide better sealing and is reusable. It is quicker and easier to use compared to the paper gasket, because using a paper gasket requires cleaning the hub when the axle shaft is removed.
