Porsche Cayenne 957 M55.1 Engine Front Differential Transfer Box Case Front Axle 4460310021 - Original Used Part

Diagnosis and Common Symptoms

As a senior technician, I frequently see the 957 Cayenne front differential assembly suffer from internal bearing fatigue or gear lash issues. Failure of the 4460310021 unit typically presents as a speed-dependent whining or grinding noise emanating from the front footwell area. You may also experience a "binding" sensation or shuddering during low-speed tight maneuvers, such as parking. If you drain the gear oil and find significant metallic "glitter" or shavings, the internal carrier bearings or the ring and pinion set have likely compromised their hardened surfaces. Mechanical failure in this unit rarely throws a direct OBDII fault code, but it can lead to drivetrain vibration that mimics a failing prop shaft or CV axle.

Introduction

This is a Genuine Porsche factory-sourced front differential housing and internal assembly, salvaged from a donor vehicle with the M55.1 engine configuration. Unlike aftermarket replacements that often struggle with precise gear mesh tolerances, this Genuine used part maintains the exact metallurgy and gear ratios required for your Cayenne's drivetrain. Every unit has been bench-tested and manually rotated to ensure smooth operation and the absence of internal play.
