Axle Assembly – GM (85580704)

Axle Assembly transfers drive across a moving joint. Two shafts that look alike can differ in length by enough to bottom out in the joint, so the measurement matters more than the model year.

Replace the Axle when there is rotational play at a joint, when the shaft is bent, or when a seal surface is grooved past the point of sealing. Measure the installed length against the specification.

The Axle in this listing carries part number 85580704 and sits in the Axle Assemblies category. The number stamped on the original part is the only reliable cross-reference.

The stock here is genuine GM, and this Axle keeps the original engineering number, which matters once a number has been superseded more than once.

Supplied as an assembly rather than as an individual component, so check that you need the whole item before ordering.
