ZF 5838.083.016 REAR AXLE | OEM Genuine Part

Overview

The ZF 5838.083.016 REAR AXLE is a critical load-bearing and torque-transmitting component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part, identified by SKU 5838.083.016, serves as the primary structural link between the differential housing and the wheel hub, ensuring precise alignment of the axle shaft under extreme radial and axial loads. Designed to withstand the punishing conditions of earthmoving and mining equipment, this rear axle integrates directly with the 5838300626: DIFFERENTIAL HOUSING to maintain drivetrain integrity. Without this component, the entire wheel-end assembly loses its geometric stability, leading to accelerated wear on surrounding gears and bearings.

Symptoms of Failure

• Persistent oil seepage at the wheel seal: When the rear axle surface becomes scored or pitted, the wheel seal loses its sealing surface, causing gear oil to leak onto brake components.
• Abnormal clunking during directional changes: A worn or bent rear axle creates excessive backlash in the final drive, producing a distinct metallic knock when shifting from forward to reverse.
• Uneven tire wear and vibration: A compromised axle shaft allows the hub to wobble, resulting in accelerated tread wear on one side and a low-frequency vibration that intensifies at higher travel speeds.
• Increased operating temperature near the hub: Friction from a misaligned rear axle forces the 0750117075: TAPER ROLLER BEARING to run hot, often exceeding normal operating ranges by 20-30°C.

Technical Specifications

Compatibility

This rear axle is engineered for ZF’s heavy-duty powershift transmission families, specifically the WG180, WG200, and WG210 series. It is commonly found in articulated dump trucks, wheel loaders, and graders from manufacturers such as Caterpillar, Volvo, and Liebherr that utilize ZF drivelines. The part interfaces directly with the 5838109010: DIFFERENTIAL and the 2093209023: DIFFERENTIAL assembly, making it essential for any rebuild of the final drive carrier group. Always verify spline count and bearing journal dimensions against your specific axle housing before installation.
