Overview
The ZF 2094.298.048 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part encloses the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission output to the wheels. As a load-bearing casing, it maintains precise gear alignment under extreme stress. The SKU 2094.298.048 is engineered to ZF’s exacting metallurgical standards, ensuring longevity in demanding environments such as wheel loaders and graders. This housing works in concert with the 2094101012: TRANSMISSION HOUSING to form the complete driveline enclosure.
Symptoms of Failure
- Oil seepage from axle housing seals: Cracks or porosity in the housing casting often lead to gradual gear oil leaks, visible as wet spots around the axle flange or drain plug area.
- Abnormal whining or grinding from the rear axle: A worn housing bore allows bearing race movement, causing gear misalignment and a distinct low-frequency hum during acceleration or deceleration.
- Contaminated differential oil with metallic debris: Internal fractures in the housing can shed ferrous particles into the lubricant, detected during routine oil sampling.
- Wheel end play or axle shaft misalignment: Structural fatigue in the housing mounting points permits excessive lateral movement of the axle shafts, affecting tire wear patterns.

Compatibility
This rear axle housing is primarily designed for ZF’s WG series powershift transmissions used in construction machinery. It is a direct fit for the WG180 and WG200 transmission models, commonly found in compact and mid-size wheel loaders. It also integrates with the WG310 series in certain articulated dump truck applications. For proper assembly, this housing must be paired with the 2094301036: HOUSING and the 2094298057: HOUSING to complete the differential carrier group. The 2094301071: COVER seals the rear access port on this assembly.
