Three failure modes put a school bus exhaust hanger out of service: a cracked bracket weld, a rubber isolator that has hardened, and mounting hardware corroded to the point of shear. All three leave exhaust components sitting outside their designed positions. The new guide lists 19 hanger part numbers against the OE numbers they cross-reference.

School bus exhaust hanger replacement is a one-part job if it is caught at the hanger. Deferred, it becomes a hanger, flex pipe, and muffler inlet repair. The load carried by a failed hanger does not disappear. It transfers to adjacent components and keeps accumulating damage until those fail too.Wh...

Yesterday we welcomed Congressman Zach Nunn and Acting US Labor Secretary Keith Sonderling to our Clive facility. They met the team, watched stainless exhaust systems take shape from raw tube to finished assembly, and saw what 65 years of American manufacturing looks like up close. Thank you to every Auto-jet employee who showed them what we do best.

Thanks to Amy Friedrich and Nate Schelhaas for spending time on our floor. Building exhaust parts that help get kids to school safely is the work we care about most, and it was a good day showing how it comes together.

A failed Blue Bird exhaust hanger transfers its load to the flex pipe and muffler inlet. That's what turns a hanger replacement into a three-part repair.
