Overview
The ZF 5838.043.007 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery drivelines. This part serves as the final drive housing and load-bearing structure within the rear axle assembly, transferring torque from the differential to the wheel hubs while supporting the vehicle’s static and dynamic weight. As a factory-specification component, the SKU 5838.043.007 ensures precise alignment with the ring gear and pinion set, maintaining the exact backlash and preload tolerances required for reliable operation under extreme loads. It integrates directly with the 5838109006: DIFFERENTIAL and the 2095209037: DIFFERENTIAL to form a complete torque distribution unit.
Symptoms of Failure
- Persistent oil seepage from axle seals: A worn or cracked rear axle housing allows lubricant to escape, leading to low oil levels and accelerated gear wear. This is a common failure mode for the 5838.043.007 in high-hour machines.
- Abnormal whining or grinding noise during turns: When the axle housing distorts or its bearing journals wear, the 0750117075: TAPER ROLLER BEARING loses proper preload, causing metal-on-metal contact and audible distress.
- Excessive backlash at the wheel end: Structural fatigue in the axle beam can increase clearance between the differential side gears and the axle shafts, resulting in a clunking sensation when shifting between forward and reverse.
- Visible cracks or deformation near the differential mounting flange: Impact loads or overloading can fracture the housing, requiring immediate replacement of the 5838.043.007 to prevent catastrophic driveline separation.

Compatibility
This rear axle is primarily designed for ZF’s WG180 and WG200 series power shift transmissions used in wheel loaders, telehandlers, and graders. It is also compatible with certain variants of the WG150 and WG210 drivelines where the axle housing mounting pattern matches. The 5838.043.007 works in conjunction with the 2095309059: DIFF.HOUSING to enclose the differential assembly. For proper assembly, always verify the axle tube length and brake mounting configuration against your specific machine model.
