ZF 4657.104.409 DIFFERENTIAL for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.104.409 DIFFERENTIAL is a critical torque-distribution component engineered specifically for the WG 190 and WG 210 series transmissions. Positioned within the rear axle assembly, this OEM genuine part ensures smooth power transfer between the drive wheels while compensating for speed differences during turns. The SKU 4657.104.409 is precision-machined to ZF’s exacting tolerances, guaranteeing long service life in heavy-duty industrial applications. When installed alongside the 4657101039: TRANSMISSION HOUSING, it forms the core of the drivetrain’s load-bearing structure.

Symptoms of Failure

• Whining or howling noise during turns: Worn differential gears produce a distinct metallic sound, especially when cornering under load.
• Oil leaks near the axle housing: Failed seals on the 4657.104.409 allow transmission fluid to escape, leading to low lubricant levels and overheating.
• Vibration or shuddering on acceleration: Damaged internal bearings cause uneven torque distribution, felt as a rhythmic shake through the chassis.
• Difficulty engaging or slipping in gear: Excessive backlash in the differential assembly results in delayed power delivery and erratic shifting behavior.

Technical Specifications

Compatibility

This differential is primarily designed for the ZF WG 210 series, with verified fitment in the WG 190 and WG 200 models. It also serves as a direct replacement in select WG 180 and WG 160 transmissions when paired with the correct 4657201028: HOUS.FRONT SECT and 4657201013: HOUSING REAR PART. Always verify the 0631306792: CYLINDRICAL PIN alignment before installation to ensure proper meshing.
