Overview
The ZF 2093.117.011 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine housing encloses the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the central load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 2093.117.011 is engineered to ZF’s exacting tolerances, ensuring a direct replacement that restores factory-spec drivetrain integrity. When paired with the 2093109014: DIFFERENTIAL, this housing creates a sealed environment that protects internal gears from contamination.
Symptoms of Failure
- Hydraulic oil seepage from axle housing seals: Cracks or porosity in the housing allow gear oil to escape, leaving visible drips under the machine after shutdown.
- Abnormal whining or grinding during turns: A warped or cracked housing misaligns the 0750117075: TAPER ROLLER BEARING, causing metal-on-metal contact and audible distress.
- Premature differential bearing failure: Housing distortion creates uneven preload, leading to rapid wear of the 2093209096: DIFFERENTIAL and its supporting bearings.
- Vibration under load: A compromised housing cannot maintain the rigid mounting points for the 2093309073: DIFF.HOUSING, resulting in driveline shudder during acceleration.

Compatibility
This rear axle housing is specifically designed for ZF’s heavy-duty powershift transmission series used in construction machinery. It is a direct fit for the WG180 and WG200 transmission models, commonly found in wheel loaders, graders, and dump trucks. The housing also supports the WG150 series in certain off-highway applications. Always verify your transmission model number before ordering to ensure correct spline engagement with the 0631100223: SPRING PIN and 0730300820: THRUST WASHER.

Frequently Asked Questions
Q: Can the ZF 2093.117.011 housing be repaired if cracked?
A: Welding is not recommended due to the risk of distorting critical bearing bores. Replacement with this OEM genuine part is the only reliable solution to restore proper alignment for the 2093209096: DIFFERENTIAL.
Q: What seals are needed when installing this axle housing?
A: You will require new axle shaft seals and an O-ring for the housing flange. We recommend replacing the 0750117075: TAPER ROLLER BEARING simultaneously to prevent premature wear.
Q: Is this housing compatible with the ZF WG200 transmission?
A: Yes, the 2093.117.011 is a standard fitment for the WG200 series. Ensure you also inspect the 2093309073: DIFF.HOUSING for wear during the swap.
