Overview
The ZF 4657.105.410 AXLE DISCONNECTION is a critical OEM genuine component engineered specifically for the WG190 and WG210 series transmissions. This precision-machined assembly sits within the rear section of the transmission housing, where it controls the engagement and disengagement of the axle drive. By isolating the axle when not in use, this part reduces parasitic drag, improves fuel efficiency, and extends the service life of the drivetrain. The SKU 4657.105.410 is a direct replacement for factory-installed units, ensuring seamless integration with your existing TRANSMISSION HOUSING assembly.
Symptoms of Failure
- Oil leaks at the axle disconnect seal: Worn internal seals cause transmission fluid to seep past the housing, leaving puddles under the vehicle. This is a common sign that the 4657.105.410 unit requires immediate replacement.
- Intermittent gear slipping during low-speed maneuvers: A failing axle disconnection mechanism may fail to fully lock or unlock, resulting in a momentary loss of torque transfer when turning or reversing.
- Unusual grinding or clunking noises from the transmission center: Damaged internal splines or bearings within the disconnect assembly produce metallic sounds, especially during engagement or disengagement cycles.
- Increased fuel consumption without warning lights: When the axle remains partially engaged due to a stuck disconnect, rolling resistance rises, directly impacting fuel economy.

Frequently Asked Questions
Q: Can the 4657.105.410 be installed without removing the transmission?
A: In most cases, yes. The axle disconnect is accessible from the rear of the transmission after draining the oil and removing the rear housing cover. However, always consult your service manual for specific clearance requirements.
Q: How do I know if my WG210 needs this part replaced?
A: Look for visible oil weeping around the disconnect actuator area or a gradual increase in transmission operating temperature. A diagnostic scan may also show fault codes related to axle engagement circuit pressure.
Q: Is this part interchangeable between WG190 and WG210 models?
A: Yes, the 4657.105.410 is physically identical for both series. The mounting points and internal spline count are the same, making it a direct swap across these platforms.
