ZF 4657.104.002 DIFFERENTIAL for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.104.002 DIFFERENTIAL is a critical power-distribution component engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part transfers torque from the driveshaft to the axle shafts while allowing the wheels to rotate at different speeds during turns. Positioned within the rear axle assembly, the differential works in concert with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure smooth power delivery. The SKU 4657.104.002 is precision-machined to ZF factory tolerances, guaranteeing a direct replacement without modification.

Symptoms of Failure

• Whining or howling noise during turns: Worn differential gears produce a distinct metallic sound when cornering, often indicating excessive backlash or gear tooth damage.
• Vibration under acceleration: A failing differential can cause driveline shudder or vibration, especially when load is applied, due to bearing wear or uneven gear contact.
• Oil leakage near the axle housing: Degraded seals or a cracked differential case allow transmission fluid to escape, leaving visible puddles under the vehicle and reducing lubrication.
• Difficulty turning or binding sensation: A seized or damaged differential prevents proper wheel speed differentiation, causing the vehicle to resist cornering or hop during low-speed maneuvers.

Technical Specifications

Compatibility

This differential is designed for ZF WG 190 and WG 210 series transmissions. It also fits select WG 180 and WG 200 models when paired with the correct HOUSING REAR PART. For proper installation, ensure the CYLINDRICAL PIN is aligned correctly to secure the differential within the housing assembly. Always verify your transmission model and axle configuration before ordering.
