Axle Vent – Mopar (5143951aa)

Axle Vent 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 Vent 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 Vent in this listing carries part number 5143951aa and sits in the Axle Assemblies category. The number stamped on the original part is the only reliable cross-reference.

Genuine MOPAR supplied for this Axle Vent, with the engineering number unchanged from the factory reference stamped on the original.
