ZF 2099.117.015 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.015 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine housing encloses the differential gear set 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 part number 2099.117.015 is specifically engineered to withstand high-impact loads in excavators, wheel loaders, and graders. When installed, it works in direct conjunction with the 2099109008: DIFFERENTIAL and the 2093309073: DIFF.HOUSING to create a sealed, lubricated environment for the rotating gears.

Symptoms of Failure

• Visible oil seepage from axle housing seals: Cracks or porosity in the housing casting allow gear oil to escape, leading to low lubricant levels and potential overheating.
• Abnormal whining or grinding noise during turns: A warped or cracked housing misaligns the 2093209096: DIFFERENTIAL, causing uneven gear mesh and metallic grinding sounds.
• Contaminated gear oil with metallic debris: Internal fractures shed metal particles into the lubricant, which can clog filters and damage the 0750117075: TAPER ROLLER BEARING.
• Wheel hub wobble or uneven tire wear: Structural failure of the housing flange compromises axle alignment, resulting in vibration and accelerated tire degradation.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty transmission families commonly used in construction machinery. It is a direct fit for the WG180 and WG200 series power shift transmissions. Additionally, it is compatible with the WG120 and WG150 series when used in articulated dump trucks and wheel loaders. Always verify the axle flange pattern and differential carrier size against your specific machine model before installation.
