ZF 2099.053.003 REAR AXLE | OEM Genuine Part

Overview

The ZF 2099.053.003 REAR AXLE is a critical load-bearing and torque-transferring component engineered for heavy-duty construction machinery. This OEM genuine part sits at the final drive stage of the transmission assembly, converting rotational power from the differential into tractive force at the wheels. Designed to withstand extreme axial and radial loads, the SKU 2099.053.003 ensures precise alignment of the axle shafts within the housing, directly influencing machine stability and drivetrain efficiency. When paired with a robust DIFFERENTIAL HOUSING, this rear axle maintains consistent gear mesh under high-stress operating conditions.

Symptoms of Failure

• Persistent oil seepage at axle seals: Worn bearings or housing distortion cause lubricant to escape, leading to contamination and accelerated gear wear.
• Low-speed grinding or whining noise: Damaged axle splines or misalignment produce metallic sounds during turns or under load, often indicating imminent failure.
• Uneven tire wear or vibration: A bent or fatigued rear axle disrupts wheel geometry, causing rhythmic shaking that worsens at higher speeds.
• Intermittent loss of traction: Excessive play in the axle shaft prevents full engagement with the CROWN WHEEL, resulting in momentary power loss during acceleration.

Technical Specifications

Compatibility

This rear axle is designed for integration with ZF’s WG180, WG200, and WG210 series powershift transmissions commonly used in wheel loaders, graders, and excavators. It directly interfaces with the DIFFERENTIAL assembly (SKU 2099109002) and the DIFFERENTIAL unit (SKU 2099209001) in dual-axle configurations. For optimal performance, always verify housing compatibility with the DIFFERENTIAL HOUSING (SKU 2098309010) to ensure correct spline engagement and bearing preload.
