Overview
The ZF 2098.109.043 DIFFERENTIAL is a critical torque-distributing component within the final drive assembly of heavy-duty construction machinery transmissions. It transfers rotational force from the driveshaft to the axle shafts, allowing wheels to rotate at different speeds during turns. As an OEM genuine part, SKU 2098.109.043 ensures precise gear mesh and load handling under extreme operating conditions. This differential sits between the bevel gear set and the axle housing, directly coupling with the DIFFERENTIAL assembly to manage power flow in ZF drivelines.
Symptoms of Failure
- Grinding noise during turns — Worn internal gears cause harsh metallic sounds when cornering under load, indicating the differential carrier needs replacement.
- Oil leaks from axle housing — Degraded seals around the differential unit allow transmission fluid to escape, visible as drips near the differential housing.
- Uneven tire wear or wheel hop — A failing differential fails to distribute torque evenly, leading to premature tire wear or vibration during straight-line operation.
- Clunking on acceleration — Excessive backlash from worn gears produces a distinct clunk when engaging the drivetrain, often accompanied by reduced traction.

Compatibility
This differential is engineered for ZF WG180, WG200, and WG250 series transmissions commonly found in wheel loaders, graders, and dump trucks. It also fits select ZF 4WG-200 and 6WG-200 drivelines used in construction machinery from 2005 onward. The 2098.109.043 differential works in tandem with the BEVEL GEAR SET to reduce speed and increase torque, while the DIFF.HOUSING provides structural support. A SPRING PIN secures the differential carrier to the axle shaft, preventing rotational slippage during heavy loads.
