Overview
The ZF 2094.211.021 REAR AXLE SHAFT is a critical driveline component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits torque from the differential gearset to the wheel hub, ensuring smooth power delivery under heavy loads. Positioned within the rear axle housing assembly, the SKU 2094.211.021 interfaces directly with the 2094101012: TRANSMISSION HOUSING and the 2094301036: HOUSING to maintain precise axial alignment. Its hardened steel construction resists torsional fatigue, making it indispensable for industrial vehicles operating in demanding environments.
Symptoms of Failure
- Rear axle oil leakage near wheel seal: A worn shaft surface damages the 0750111371: SHAFT SEAL, causing fluid to escape and contaminating brake components.
- Intermittent gear slipping under load: Spline wear on the shaft prevents positive engagement with the differential side gears, leading to power loss during acceleration.
- Vibration or humming from the rear differential: Bearing journal wear on the 2094.211.021 creates radial play, producing low-frequency noise that intensifies at highway speeds.
- Metallic debris in transmission fluid: Flaking from the shaft’s hardened surface circulates through the system, accelerating wear on the 2094298057: HOUSING and internal gears.

Compatibility
This rear axle shaft is precision-machined for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants when used with the 2094301071: COVER adapter. Always verify spline count and bearing journal dimensions against your existing assembly. The shaft integrates with the 2094301030: GASKET and 0631306670: CYLINDRICAL PIN for proper alignment during installation.
