Axle Assembly – GM (42758447)

Axle Assembly is a rotating or reciprocating member that transmits force. Spline count and end configuration are specific to the application and are not visible from a photograph.

Replace the Axle when a vibration is felt under acceleration only, or when a spline is worn and rocking in its coupling. Worn splines are not repairable.

This Axle is listed under part number 42758447, filed under Axle Assemblies. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

The stock here is genuine GM, and this Axle keeps the original engineering number, which matters once a number has been superseded more than once.

This is sold as an assembly; if only one component has failed, confirm whether the single part is available separately.
