Overview
The ZF 5838.053.007 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery drivelines. This part functions as the primary output hub within the final drive assembly, transferring rotational torque from the differential directly to the wheel hubs. Designed to withstand extreme axial and radial loads in demanding environments like excavators and wheel loaders, the 5838.053.007 ensures precise alignment of the axle shafts. When paired with a 5838109017: DIFFERENTIAL, this rear axle forms the backbone of the vehicle’s traction system, converting high-speed transmission output into usable low-speed, high-torque motion.
Symptoms of Failure
- Excessive driveline backlash or “clunking” during acceleration: A worn ZF 5838.053.007 rear axle often causes a noticeable delay or metallic knock when shifting from neutral to drive, indicating spline or bearing surface degradation.
- Persistent oil seepage around the axle hub seal: If you notice gear oil leaking from the wheel-end area, the axle’s sealing surface may be scored or pitted, compromising the integrity of the 0750117075: TAPER ROLLER BEARING housing.
- Vibration at low operating speeds (5-15 mph): A failing rear axle can produce a rhythmic shudder felt through the chassis, often caused by uneven wear on the axle shaft or a misaligned 2095209037: DIFFERENTIAL carrier.
- Abnormal tire wear patterns on one side: When the axle loses its rotational trueness, it forces the wheel to track incorrectly, leading to scalloped or feathered tire edges.

Compatibility
This OEM genuine rear axle is primarily designed for integration into ZF’s heavy-duty transmission families used in construction machinery. It is a direct fit for the WG180 and WG200 series power shift transmissions, commonly found in articulated dump trucks and graders. The 5838.053.007 also serves as a replacement component in certain WG150 and WG250 final drive assemblies where the axle interfaces with the 2095309059: DIFF.HOUSING. Always verify the spline count and overall length against your existing unit before installation.
