ZF 2099.117.038 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.038 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine housing encases the differential and crown wheel gear set, providing the rigid mounting point for axle shafts and bearings. As the primary load-bearing shell, it maintains precise gear alignment under extreme torque loads. The part number 2099.117.038 is engineered to ZF’s original specifications, ensuring exact fitment and metallurgical integrity for demanding off-road applications.

Symptoms of Failure

• Oil seepage at axle tube seals: A cracked or warped housing often causes lubricant to escape past the seal surfaces, leading to low oil levels and potential gear damage.
• Abnormal whining or grinding from the rear axle: When the housing distorts, the 2098309008: CROWN WHEEL and pinion gear lose proper mesh, creating a constant, load-dependent noise.
• Premature bearing failure: A fatigued housing allows the 2099109038: DIFFERENTIAL carrier to shift, placing uneven stress on bearings and causing rapid wear.
• Vibration during acceleration: Structural flex in the housing permits the 2098209016: DIFFERENTIAL assembly to oscillate, transmitting harsh vibrations through the chassis.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series used in construction equipment. It is a direct fit for the WG180 and WG200 transmission models, commonly found in wheel loaders, graders, and dump trucks. The housing also supports the WG150 series when paired with the correct 2095309059: DIFF.HOUSING adapter. Always verify your transmission serial number against ZF’s application guide before installation.
