Overview
The ZF 2094.117.003 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encloses the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As a load-bearing casing, it protects internal gears from contaminants while maintaining precise alignment under extreme stress. The SKU 2094.117.003 is engineered to ZF’s exacting tolerances, ensuring a seamless fit with the 2094101012: TRANSMISSION HOUSING and the 2094301036: HOUSING to form a sealed, leak-free drivetrain assembly.
Symptoms of Failure
- Hydraulic oil seepage from axle housing seals: When the rear axle housing warps or develops micro-fractures, oil leaks appear around the mounting flanges, often mistaken for simple seal failure.
- Unusual whining or grinding during turns: A compromised housing allows the differential carrier to shift, causing gear tooth misalignment and audible metal-on-metal contact.
- Excessive backlash in the driveline: Worn bearing bores within the housing lead to increased play between the ring and pinion gears, resulting in a clunking sensation when shifting between forward and reverse.
- Contaminated gear oil with metallic debris: Cracks in the housing permit abrasive particles to enter the lubrication system, accelerating wear on the 2094298057: HOUSING and internal bearings.

Compatibility
This rear axle housing is designed for ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and telehandlers. It directly fits the WG180 and WG200 transmission models, as well as select variants of the WG310 series. The housing interfaces with the 2094301071: COVER to seal the differential cavity, and it requires proper torque sequencing when bolted to the main transmission case. Always verify the axle ratio stamp on your existing housing before replacement.
