Overview
The ZF 2095.317.011 REAR AXLE HOUSING is a structural core component designed for heavy-duty construction machinery drivelines. This OEM genuine part encases the differential assembly and final drive gears, providing rigid support and precise alignment for the axle shafts. As a load-bearing housing, it protects internal rotating elements from contaminants while maintaining correct gear mesh under extreme torque loads. The SKU 2095.317.011 is specifically engineered to integrate with ZF’s modular transmission systems, ensuring that the axle assembly maintains its geometric integrity during high-stress earthmoving and material handling operations.
Symptoms of Failure
- Rear axle housing oil seepage at seal mating surfaces: Cracks or porosity in the housing casting often lead to gradual lubricant loss, visible as wet patches around the differential mounting flange or axle tube ends.
- Abnormal gear whine during loaded turns: A warped or fatigued housing can misalign the 2095109012: DIFFERENTIAL assembly, causing uneven tooth contact and a distinct cyclical noise under cornering loads.
- Premature bearing failure on the output side: Housing bore distortion accelerates wear on the 0750117075: TAPER ROLLER BEARING, resulting in detectable radial play at the wheel hub.
- Recurring differential carrier bolt loosening: Housing flex under load can cause the mounting points for the 2095209037: DIFFERENTIAL to fatigue, leading to fastener relaxation and internal component shift.

Compatibility
This rear axle housing is primarily specified for ZF WG180 and WG200 series power shift transmissions used in wheel loaders, telehandlers, and graders. It also fits select ZF 4WG-180 and 4WG-200 drivelines where the axle housing interfaces with the 2095309059: DIFF.HOUSING sub-assembly. The casting accommodates both standard and limited-slip differential configurations from the WG family. Always verify the axle ratio and brake mounting pattern before installation, as minor variations exist between early and late production units.
