Overview
The ZF 2095.056.017 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This part transmits rotational power from the differential housing directly to the wheel hubs, ensuring consistent torque delivery under extreme load conditions. As a factory-spec replacement, the SKU 2095.056.017 integrates seamlessly with ZF’s planetary gear sets to maintain driveline integrity. When paired with a properly functioning 2095109019: DIFFERENTIAL, this rear axle minimizes backlash and supports sustained operation in excavators, wheel loaders, and graders.
Symptoms of Failure
- Oil seepage at axle seal interface: Worn journals on the 2095.056.017 allow lubricant to escape, leading to low gear oil levels and accelerated internal wear.
- Audible clunking during direction changes: Excessive clearance between the axle shaft and the 2095209037: DIFFERENTIAL produces metallic knocking sounds under load reversal.
- Vibration at operating speeds: A bent or fatigued rear axle causes harmonic oscillations that resonate through the chassis, often misdiagnosed as wheel imbalance.
- Uneven tire wear patterns: Misalignment from a compromised axle forces the 0750117075: TAPER ROLLER BEARING to carry uneven loads, scrubbing tire treads prematurely.

Compatibility
This OEM rear axle is designed for ZF’s WG180, WG200, and WG211 series power shift transmissions commonly found in Construction Machinery. It directly replaces the axle shaft in single-reduction final drives for models including the ZF 4WG-180, 4WG-200, and 5WG-211. The 2095.056.017 also interfaces with the 2095309059: DIFF.HOUSING in these assemblies. Always verify spline count and overall length against your existing part before installation.
