Overview
The ZF 2094.317.006 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 mounting point for wheel hubs and absorbing immense torsional loads during operation. As the primary load-bearing shell for the rear axle, the housing ensures precise gear alignment and protects internal lubricants from contamination. The SKU 2094.317.006 is engineered to ZF’s exacting tolerances, making it a direct replacement for worn or damaged housings in demanding earthmoving and material handling equipment.
Symptoms of Failure
- Persistent oil seepage from axle tube welds: When the housing cracks or corrodes, gear oil leaks onto brake assemblies, causing reduced stopping power and visible puddles under the machine.
- Abnormal whining or grinding from the rear axle: A warped or misaligned housing forces differential bearings out of spec, producing a rhythmic noise that intensifies under load.
- Premature wheel seal failure: A distorted housing bore causes the shaft seal to wear unevenly, leading to repeated seal blowouts and contamination of the hub oil.
- Vibration during straight-line travel: A cracked housing allows the axle shafts to flex, transmitting low-frequency vibrations through the chassis that worsen with speed.

Compatibility
This rear axle housing is designed for ZF’s heavy-duty powershift transmission series, specifically the WG180 and WG200 models found in wheel loaders, graders, and dump trucks. It also fits select WG150 and WG250 variants equipped with planetary final drives. Always verify the axle flange pattern and tube length against your existing housing before ordering.
Installation Context
When replacing the rear axle housing, it is essential to inspect the 2094101017: TRANSMISSION HOUSING for cracks at the mating flange, as misalignment here accelerates housing wear. The 2094301069: HOUSING for the differential carrier must be torqued to spec to prevent gear backlash. Additionally, the 2094298054: HOUSING for the input shaft should be checked for pitting. Finally, always install a new 0636302008: SCREW PLUG to seal the fill port and avoid contamination.
