ZF 4657.104.013 DIFFERENTIAL for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.104.013 DIFFERENTIAL is a critical power-distribution component engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part manages torque split between the drive wheels while allowing rotational speed differences during cornering, ensuring stable vehicle handling under heavy loads. As a precision-machined assembly, the differential sits within the rear axle housing and interfaces directly with the output shaft. The SKU 4657.104.013 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in construction and agricultural machinery. For complete transmission integrity, this differential works in concert with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain driveline alignment.

Symptoms of Failure

• Whining or howling noise during turns: Worn differential gears produce a distinct metallic whine, especially audible when the vehicle is cornering under load. This often indicates pitting or chipping on the gear teeth.
• Oil leaks near the axle housing: A failing differential can cause lubricant to seep past seals, leaving visible drips or wet spots around the housing. This is a common symptom when the carrier bearings or side gears degrade.
• Clunking or backlash on acceleration: Excessive play in the differential assembly leads to a pronounced clunk when shifting from drive to reverse or when applying throttle. This signals worn spider gears or a damaged cross shaft.
• Vibration at highway speeds: Imbalanced or failing differential components transmit vibration through the driveline, often felt in the cab or chassis at sustained speeds above 30 mph.

Technical Specifications

Compatibility

This differential is designed for the ZF WG 190 and WG 210 series transmissions, which are commonly used in wheel loaders, telehandlers, and heavy-duty trucks. It also fits the WG 180 and WG 200 variants when the axle housing configuration matches. The part is not compatible with the WG 150 series due to different spline dimensions. For proper installation, ensure the HOUSING REAR PART is inspected for wear, and the SPEEDOMETER drive gear is aligned correctly during reassembly.
