ZF 2095.117.022 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2095.117.022 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential gears 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 alignment for all rotating elements. The SKU 2095.117.022 is specifically engineered to withstand the extreme stress and shock loads common in excavators and wheel loaders. When paired with a 2095109012: DIFFERENTIAL, this housing ensures optimal gear mesh and long-term drivetrain reliability.

Symptoms of Failure

• Visible oil seepage from axle tube seals: Cracks or porosity in the housing casting often lead to gear oil leaking past the axle seals, leaving puddles under the machine.
• Abnormal whining or grinding noise during turns: A warped or cracked housing misaligns the differential carrier, causing the 0750117075: TAPER ROLLER BEARING to wear unevenly and generate a distinct low-frequency growl.
• Excessive backlash in the final drive: Structural fatigue in the housing allows the differential assembly to shift, resulting in a noticeable clunk when shifting between forward and reverse.
• Contaminated lubricant with metallic debris: Internal fractures shed ferrous particles into the oil, which can be detected during routine fluid analysis.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series commonly used in construction equipment. It is a direct fit for the WG180 and WG200 transmission models, as well as the WG150 series when used with a 2095209037: DIFFERENTIAL. The housing also supports the 4WG-200 and 5WG-200 variants. For proper assembly, ensure the mating 2095309059: DIFF.HOUSING is free of burrs and the bearing seats are within factory tolerances.
