ZF 2095.117.020 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2095.117.020 REAR AXLE HOUSING is a structural core component within heavy-duty construction machinery drivelines. This OEM genuine part encloses the final drive gearset, supporting the axle shafts and differential assembly while withstanding extreme torsional loads and shock impacts from rough terrain operations. As the primary load-bearing casing, the SKU 2095.117.020 ensures precise alignment of internal rotating elements, preventing contamination from debris and retaining lubricant under high-pressure conditions. This housing integrates directly with the transmission output to transfer power to the wheels, making it indispensable for maintaining drivetrain integrity in wheel loaders, graders, and dump trucks.

Symptoms of Failure

• Visible oil seepage from axle housing seals: When the housing develops hairline cracks or porosity, gear oil leaks around the flange joints, often leaving puddles under parked equipment. This is a common long-tail search query for “ZF rear axle housing oil leak repair.”
• Abnormal whining or grinding during turns: A warped or fatigued housing misaligns the differential carrier, causing gear teeth to clash. Operators may notice “axle housing noise when turning” as a distinct failure symptom.
• Excessive backlash in the driveline: Structural deformation allows the ring gear to shift relative to the pinion, creating a clunking sensation during acceleration or deceleration. This matches searches for “ZF axle housing backlash issues.”
• Premature bearing wear: A compromised housing no longer maintains proper preload on the 0750117075 TAPER ROLLER BEARING, leading to rapid degradation of both components.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG series powershift transmissions commonly deployed in construction machinery. It directly fits the WG180 and WG200 transmission models, which are used in articulated dump trucks and wheel loaders. The housing also supports the WG160 and WG210 variants when paired with the correct 2095309059 DIFF.HOUSING adapter kit. For optimal performance, always verify axle ratio compatibility with your specific machine model before installation.

During rebuilds, the housing works in concert with the 2095109009 DIFFERENTIAL and 2095209037 DIFFERENTIAL to distribute torque evenly. Proper seating of the 0750117075 TAPER ROLLER BEARING inside the housing bore is critical for longevity.
