ZF 2099.117.042 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.042 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encloses the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the primary load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 2099.117.042 is engineered to ZF’s exacting tolerances, ensuring a sealed environment that protects internal components from debris and contamination. This housing sits directly between the axle shafts and the differential carrier, forming the backbone of the rear drive system.

Symptoms of Failure

• Visible oil seepage from axle housing seals: Cracks or warping in the housing often cause lubricant to escape, leading to low oil levels and potential gear damage.
• Persistent whining or grinding noise during turns: A deformed housing misaligns the differential gears, creating metal-on-metal contact that worsens under load.
• Excessive backlash in the drivetrain: When the housing loses structural integrity, the 2099109030: DIFFERENTIAL can shift, causing a noticeable clunk when engaging gears.
• Uneven tire wear or vibration at speed: A compromised housing alters the pinion angle, transmitting vibration through the chassis and accelerating tire degradation.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series commonly used in construction loaders and graders. It is a direct fit for the WG180 and WG200 transmission models, as well as the WG310 series in certain configurations. The housing interfaces directly with the 2093209094: DIFFERENTIAL and the 2093309078: DIFF.HOUSING to form a sealed assembly. For proper installation, ensure the 0750117075: TAPER ROLLER BEARING is replaced simultaneously to maintain preload specifications.
