Overview
The ZF 2094.117.006 REAR AXLE HOUS. is a critical structural component designed to encase and protect the differential and final drive gears within ZF heavy-duty transmissions. This OEM genuine part ensures precise alignment of the axle shafts and ring gear, directly supporting torque transfer from the transmission to the wheels in construction machinery. The SKU 2094.117.006 serves as the primary load-bearing shell for the rear axle assembly, absorbing dynamic stresses during operation. It integrates seamlessly with the 2094101017: TRANSMISSION HOUSING to form a sealed drivetrain unit, while the 2094301069: HOUSING and 2094298054: HOUSING components work in tandem to support adjacent gear clusters.
Symptoms of Failure
- Oil seepage around the axle flange: When the 2094.117.006 housing develops micro-cracks or gasket surface wear, hydraulic fluid escapes, leading to low lubricant levels and potential gear damage.
- Unusual whining or grinding from the rear axle: A warped or misaligned housing causes the ring and pinion gears to mesh improperly, producing audible noise during acceleration or deceleration.
- Vibration during load cycles: Structural fatigue in the housing allows the differential carrier to shift, transmitting vibrations through the chassis under heavy loads.
- Contaminated differential oil: Cracks in the housing permit debris ingress, which accelerates wear on bearings and seals, often requiring replacement of the 0636302008: SCREW PLUG and associated sealing components.

Compatibility
This rear axle housing is engineered for ZF WG-series transmissions commonly deployed in wheel loaders, graders, and dump trucks. It is directly compatible with the WG180, WG200, and WG220 models, where it mounts to the transmission output flange. The housing also fits select variants of the ZF 4WG-200 and 6WG-200 series used in construction machinery from manufacturers like Volvo, Caterpillar, and Liebherr. Always verify the bolt pattern and axle ratio before installation.
