# Service bulletin SB\-23\-31\-004

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's summary

On some Semi vehicles, the Efficiency Drive Axle \(EDA\) and Torque Drive Axle \(TDA\) air spring to trailing arm interfaces may have gaps. The gaps may cause uneven loading of the air spring, and may reduce spring service life.
