Product Description

- - - Function: Distributes Haldex-5 AWD torque (50:50 bias) via hypoid gearset (3.68:1 ratio) with integrated e-diff.
      
      Key Features:
      - Forged Pinion: Case-hardened steel (HRC 62+) with lapped contact pattern
      - Sealed Bearings: Lifetime lubricated (G 052 145 S2 fluid)
      - Thermal Sensor: Monitors fluid temp (>130°C triggers TCU protection)
      Failure Modes:
      - Bearing Brinelling: Impact loads create false brinelling marks (hum at 80km/h+)
      - Seal Leaks: Allows fluid migration to Haldex pump (P189C codes)
      - Crown Wheel Pitting: Improper run-in causes fatigue spalling
      Critical Specs:
      1. Backlash: 0.08-0.15mm (requires dial indicator)
      2. Pinion preload: 1.0-1.5 Nm rotational torque
      Pro Tip: Post-installation, perform 30km run-in with varied speeds – avoids glazing.
