ZF 4657.104.414 DIFFERENTIAL for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.104.414 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 core of the final drive assembly, managing the speed difference between the left and right output shafts while delivering power from the transmission to the axles. As a precision-machined unit, the SKU 4657.104.414 ensures smooth cornering and reduces drivetrain stress in heavy-duty industrial applications. It integrates directly with the 4657101080: TRANSMISSION HOUSING and is flanked by the 4657201167: HOUS.FRONT SECT to maintain structural integrity under high load cycles.

Symptoms of Failure

• Low-speed grinding or whining noise — Worn differential gears produce a distinct metallic sound during turns, often misdiagnosed as wheel bearing failure.
• Uneven tire wear and traction loss — A failing differential cannot properly distribute torque, causing one wheel to spin excessively on loose surfaces or during acceleration.
• Oil seepage near the axle seals — Degraded internal seals allow hypoid oil to leak past the housing, leaving visible drips under the vehicle after extended operation.
• Clunking during gear engagement — Excessive backlash in the differential assembly creates a pronounced thud when shifting from neutral to drive or reverse.

Technical Specifications

Compatibility

This differential is primarily designed for the ZF WG 210 series, with verified fitment in the WG 190 models. It is also compatible with earlier WG 180 and WG 200 transmissions when paired with the correct 4657201171: HOUSING REAR PART and 4657298103: HOUSING REAR SECTION. Always verify the housing bore dimensions before installation, as the differential interfaces directly with the 4657101080: TRANSMISSION HOUSING to ensure proper alignment of the ring gear.
