Overview
The ZF 5838.023.007 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This precision-machined axle transmits torque from the differential to the wheel hubs, ensuring stable power delivery under extreme loads. Positioned within the rear axle housing, it directly interfaces with the 5838109007: DIFFERENTIAL and the 2095209019: DIFFERENTIAL to manage rotational forces. The SKU 5838.023.007 is manufactured to ZF’s strict tolerances, making it a direct replacement for worn units in off-highway vehicles like wheel loaders and graders.
Symptoms of Failure
- Oil leaks near the wheel hub: A worn rear axle shaft seal allows differential oil to escape, leaving visible puddles under the machine.
- Axle shaft spline wear causing gear slipping: When the splines strip, the axle fails to engage the differential, resulting in intermittent power loss during acceleration.
- Excessive end-play or vibration: Bearing surface degradation on the axle creates lateral movement, felt as a rhythmic shudder through the chassis at low speeds.
- Metallic grinding noises: Debris from a failing 0750117075: TAPER ROLLER BEARING can score the axle journal, producing a distinct grinding sound during turns.

Compatibility
This rear axle is designed for ZF’s WG180, WG200, and WG310 series power-shift transmissions commonly used in construction machinery. It fits final drive assemblies where the axle interfaces with the 5838300682: DIFFERENTIAL AXLE and associated thrust washers. Always verify the axle housing dimensions and spline count against your specific transmission model before installation.
