Overview
The ZF 4657.105.415 AXLE DISCONNECTION is a critical OEM genuine component engineered specifically for the WG 210 Series transmission. This precision-machined assembly sits within the driveline housing, where it selectively engages and disengages the front axle to optimize fuel efficiency and reduce mechanical drag during highway operation. The SKU 4657.105.415 interfaces directly with the 4657101051: TRANSMISSION HOUSING and the 4657201151: HOUS.FRONT SECT to form a sealed, high-torque pathway. By isolating the axle when not needed, this part prevents unnecessary wear on downstream components and maintains consistent hydraulic pressure across the system.
Symptoms of Failure
- Intermittent axle engagement failure – The transmission fails to lock or unlock the front axle, causing a grinding sensation during low-speed turns or when shifting between 2WD and 4WD modes.
- Hydraulic fluid seepage near the disconnect housing – Worn seals on the 4657.105.415 allow ATF to leak past the actuator bore, leaving puddles under the vehicle and reducing system pressure.
- Unusual whining or clunking from the driveline – A failing axle disconnection unit produces a metallic chatter that intensifies under load, often mistaken for differential noise.
- Dashboard warning light for transmission or axle system – The ECU detects a mismatch between commanded and actual axle state, triggering a fault code that requires immediate inspection.

Compatibility
This axle disconnection unit is designed for the ZF WG 210 Series, but it also fits select models in the WG180 and WG200 families due to shared housing architecture. The part is fully compatible with transmissions that utilize the 4657201103: HOUSING REAR PART and the 4472239184: HOUSING REAR PART. Always verify your transmission serial number before ordering to ensure correct fitment.

Frequently Asked Questions
Q: Can the 4657.105.415 be repaired, or must it be replaced?
A: This axle disconnection unit is a sealed assembly. While external seals can sometimes be replaced, internal wear on the actuator splines or piston bore typically requires full replacement to restore reliable operation.
Q: How do I confirm this part fits my WG210 transmission?
A: Check the transmission data plate for the model code (e.g., WG210-XXX). The 4657.105.415 is standard on all WG210 variants, but verify that your housing uses the same bolt pattern as the 4657201103: HOUSING REAR PART.
Q: What torque specification is required for the cap screws during installation?
A: Use 85 Nm for the 0636100801: CAP SCREW and 110 Nm for the 0636100803: CAP SCREW. Always apply thread locker to prevent loosening in high-vibration environments.
