Overview
The ZF 5838.046.004 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery drivelines. This part serves as the final drive housing and torque transfer hub within the rear axle assembly, directly connecting the differential output to the wheel ends. Designed to withstand extreme loads and torsional stress, the 5838.046.004 ensures precise power distribution and structural integrity in demanding off-road environments. As a genuine ZF part, it guarantees exact fitment and metallurgical consistency, reducing downtime in excavators, wheel loaders, and graders. The SKU 5838.046.004 is often replaced in conjunction with the 5838109006: DIFFERENTIAL to restore full axle performance.
Symptoms of Failure
- Rear axle oil seepage around hub seals: When the 5838.046.004 housing develops micro-cracks or seal surface wear, gear oil leaks become visible, often pooling inside the wheel rim.
- Abnormal whining or grinding noise during turns: A worn rear axle can cause misalignment of the 0750117075: TAPER ROLLER BEARING, producing metallic sounds under load.
- Excessive backlash or driveline clunking: Fatigue in the axle shaft splines leads to play between the differential and wheel hub, creating a distinct clunk on acceleration or deceleration.
- Uneven tire wear or vibration at low speeds: A bent or fatigued rear axle disturbs the rotational balance, causing lateral runout and premature tire scalloping.

Compatibility
This genuine ZF rear axle is primarily compatible with ZF WG180, WG200, and WG210 series power-shift transmissions used in construction machinery. It is designed for rigid rear axles in models such as the ZF APL-300, APL-350, and APL-400 series. The 5838.046.004 interfaces directly with the 2095209037: DIFFERENTIAL and the 2095309059: DIFF.HOUSING to form the complete final drive assembly. Always verify axle ratio and spline count against your specific machine’s service manual before installation.
