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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10184788-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10184788-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10184788","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"WESTERN STAR","model":"4700","year_from":2002,"year_to":2021,"match":"exact","vehicle_ids":["2002_western-star_4700","2003_western-star_4700","2004_western-star_4700","2005_western-star_4700","2006_western-star_4700","2007_western-star_4700","2008_western-star_4700","2009_western-star_4700","2010_western-star_4700","2011_western-star_4700","2012_western-star_4700","2013_western-star_4700","2014_western-star_4700","2015_western-star_4700","2016_western-star_4700","2017_western-star_4700","2018_western-star_4700","2019_western-star_4700","2020_western-star_4700","2021_western-star_4700"]},{"make":"WESTERN STAR","model":"4800","year_from":2004,"year_to":2021,"match":"exact","vehicle_ids":["2004_western-star_4800","2005_western-star_4800","2006_western-star_4800","2007_western-star_4800","2008_western-star_4800","2009_western-star_4800","2010_western-star_4800","2011_western-star_4800","2012_western-star_4800","2013_western-star_4800","2014_western-star_4800","2015_western-star_4800","2016_western-star_4800","2017_western-star_4800","2018_western-star_4800","2019_western-star_4800","2020_western-star_4800","2021_western-star_4800"]},{"make":"WESTERN STAR","model":"4900","year_from":2002,"year_to":2021,"match":"exact","vehicle_ids":["2002_western-star_4900","2003_western-star_4900","2004_western-star_4900","2005_western-star_4900","2006_western-star_4900","2007_western-star_4900","2008_western-star_4900","2009_western-star_4900","2010_western-star_4900","2011_western-star_4900","2012_western-star_4900","2013_western-star_4900","2014_western-star_4900","2015_western-star_4900","2016_western-star_4900","2017_western-star_4900","2018_western-star_4900","2019_western-star_4900","2020_western-star_4900","2021_western-star_4900"]},{"make":"WESTERN STAR","model":"49X","year_from":2021,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"WESTERN STAR","model":"5700","year_from":2015,"year_to":2021,"match":"exact","vehicle_ids":["2015_western-star_5700","2016_western-star_5700","2017_western-star_5700","2018_western-star_5700","2019_western-star_5700","2020_western-star_5700","2021_western-star_5700"]},{"make":"WESTERN STAR","model":"6900","year_from":2002,"year_to":2021,"match":"exact","vehicle_ids":["2002_western-star_6900","2003_western-star_6900","2004_western-star_6900","2005_western-star_6900","2006_western-star_6900","2007_western-star_6900","2008_western-star_6900","2009_western-star_6900","2010_western-star_6900","2011_western-star_6900","2012_western-star_6900","2013_western-star_6900","2014_western-star_6900","2015_western-star_6900","2016_western-star_6900","2017_western-star_6900","2018_western-star_6900","2019_western-star_6900","2020_western-star_6900","2021_western-star_6900"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
