Overview
The ZF 5838.117.010 REAR AXLE HOUS. is a critical structural component designed to enclose and protect the differential and final drive gearset within ZF heavy-duty transmissions. This OEM genuine part serves as the rigid mounting point for the axle shafts and bearings, ensuring precise alignment of rotating elements under extreme torque loads. The SKU 5838.117.010 is precision-machined from high-strength cast iron to withstand the punishing conditions found in construction machinery, including excavators, wheel loaders, and graders. As the primary housing for the differential assembly, it directly interfaces with the 5838109007: DIFFERENTIAL and supports the 0750117075: TAPER ROLLER BEARING that carries axial and radial loads during operation.
Symptoms of Failure
- Oil leaks at axle seal interface: A cracked or warped rear axle housing often manifests as persistent gear oil seepage around the axle flange, leading to low lubricant levels and accelerated wear.
- Abnormal gear noise during turns: When the housing loses structural integrity, the differential carrier shifts out of alignment, causing a distinct whining or grinding sound when the machine maneuvers under load.
- Premature bearing failure: Distortion in the housing bore causes uneven loading on the 2095209019: DIFFERENTIAL and its associated bearings, resulting in metal shavings in the oil and eventual seizure.
- Vibration through the driveline: A compromised housing allows the axle shafts to wobble, transmitting harsh vibrations to the chassis during acceleration or deceleration.

Compatibility
This rear axle housing is engineered for ZF’s WG series powershift transmissions commonly deployed in construction machinery. It is a direct fit for the WG180 and WG200 transmission models, as well as the WG150 series used in mid-size wheel loaders. The housing also supports the WG250 heavy-duty variant found in large excavators. When replacing this component, always inspect the 0631329086: SPRING PIN that secures the differential carrier, as this pin is prone to shearing under high torque conditions.
