Overview
The ZF 2095.009.031 T 7117 L is an OEM genuine differential component engineered for heavy-duty construction machinery transmissions. This precision-machined part integrates directly into the final drive assembly of ZF power shift transmissions, where it manages torque distribution between the axle shafts. As a critical load-bearing element, the 2095.009.031 ensures smooth power transfer under extreme operating conditions. When replacing this unit, technicians often inspect the 2095109011: DIFFERENTIAL and 2095209037: DIFFERENTIAL for simultaneous wear, as these components share the same lubrication circuit and stress loads.
Symptoms of Failure
- Low-speed grinding noise from axle housing: When the 2095.009.031 wears, metallic grinding sounds occur during tight turns or under load, indicating damaged gear teeth or bearing surfaces.
- Oil leaks at differential carrier seal: Worn mating surfaces cause transmission fluid to seep past the housing, leaving visible drips on the axle casing after operation.
- Intermittent wheel hop during acceleration: A failing unit disrupts torque bias, causing one wheel to spin momentarily before catching, especially on uneven terrain.
- Excessive backlash in driveline: Operators notice a clunk when shifting between forward and reverse, signaling internal clearance has exceeded factory tolerances.

Compatibility
This OEM genuine part is designed for ZF WG-series powershift transmissions commonly used in wheel loaders, graders, and telehandlers. It is a direct fit for the ZF WG180, WG200, and WG210 models. The 2095.009.031 also appears in certain ZF T 7117 L final drive assemblies found in older Liebherr and Volvo construction equipment. For proper installation, always pair this unit with a new 0750117075: TAPER ROLLER BEARING and inspect the 2095309059: DIFF.HOUSING for cracks or scoring.
