Overview
The ZF 5838.052.007 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This part transmits rotational torque from the differential directly to the wheel hubs, ensuring reliable power delivery under extreme load conditions. As a precision-machined axle shaft, it sits within the axle housing and interfaces directly with the differential side gears. The SKU 5838.052.007 is manufactured to ZF’s original tolerances, guaranteeing a direct fit and long service life in demanding environments such as wheel loaders and graders.
Symptoms of Failure
- Rear axle oil leaks at the wheel seal: When the axle shaft surface becomes scored or pitted, the wheel-end seal fails, allowing gear oil to escape and contaminating brake components.
- Excessive drivetrain backlash or clunking: A worn or fatigued 5838.052.007 axle can develop spline wear, causing a noticeable delay in power engagement when shifting between forward and reverse.
- Vibration during straight-line travel: A bent or cracked rear axle produces a rhythmic vibration that intensifies with vehicle speed, often misdiagnosed as a tire imbalance.
- Uneven tire wear patterns: Axle runout beyond specification leads to lateral wheel movement, accelerating shoulder wear on drive tires.

Compatibility
This rear axle is designed for use in ZF’s heavy-duty transmission families, specifically the WG180 and WG200 series. It is also compatible with select WG310 and WG350 final drive assemblies found in articulated dump trucks and large wheel loaders. Always verify the axle housing configuration and differential type before installation. The 5838.052.007 works in tandem with the 5838109006 DIFFERENTIAL and the 2095209037 DIFFERENTIAL to distribute torque evenly. Proper alignment is ensured by the 0750117075 TAPER ROLLER BEARING which supports the axle shaft, while the 2095309059 DIFF.HOUSING encloses the entire assembly.
