ZF 4657.104.010 DIFFERENTIAL for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.104.010 DIFFERENTIAL is a critical torque-distribution component engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part sits at the heart of the final drive assembly, managing the rotational speed difference between the left and right output shafts while transmitting engine power to the wheels. The SKU 4657.104.010 is precision-machined to ensure seamless integration with the 4657101039: TRANSMISSION HOUSING and the 4657201028: HOUS.FRONT SECT, forming a robust load-bearing unit. Without a properly functioning differential, the transmission cannot compensate for wheel speed variations during turns, leading to driveline binding and premature wear.

Symptoms of Failure

When the ZF 4657.104.010 differential begins to fail, operators will notice distinct performance issues. Oil leaks from the differential housing area are a common early indicator, often caused by degraded seals or bearing wear. Gear slipping or clunking noises during low-speed turns signal that the differential gears are losing mesh integrity. Vibration through the chassis under load typically points to worn spider gears or damaged thrust washers. Uneven tire wear or wheel hop during acceleration can also occur, as the differential fails to distribute torque evenly between the drive wheels.

Technical Specifications

Compatibility

This differential is designed primarily for the ZF WG 210 and ZF WG 190 transmission series. It also fits select variants of the WG 180 and WG 200 models, provided the axle housing configuration matches. The part interfaces directly with the 4657201013: HOUSING REAR PART and is secured using the 0631306792: CYLINDRICAL PIN for precise alignment. Always verify your transmission’s serial number against ZF’s compatibility chart before installation.
