ZF 2099.117.005 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.005 REAR AXLE HOUS. is a structural core component within heavy-duty construction machinery drivelines. This OEM genuine housing encloses the final drive gearing and differential assembly, providing the rigid mounting point for axle shafts and bearings. As the primary load-bearing casing, it withstands extreme torsional stress and shock loads during excavation and material handling. The SKU 2099.117.005 is precision-machined to maintain exact gear mesh alignment, directly influencing torque transfer efficiency to the wheels. It sits between the axle tubes and the differential carrier, forming the central chamber that houses the 2099109004: DIFFERENTIAL assembly.

Symptoms of Failure

• Hydraulic oil seepage at axle housing seals: Cracks or porosity in the housing casting allow gear oil to weep onto brake components, creating visible drips under the machine.
• Abnormal whining or grinding from rear axle: A warped housing face misaligns the 0750117075: TAPER ROLLER BEARING, causing metallic contact during rotation.
• Intermittent wheel lock-up or binding: Distorted housing bores prevent proper preload on the 2093209095: DIFFERENTIAL gears, leading to uneven power delivery.
• Visible cracks near mounting flanges: Stress fractures from repetitive loading compromise the structural integrity of the 2093309071: DIFF.HOUSING interface.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG series powershift transmissions commonly deployed in wheel loaders and telehandlers. It directly fits the WG180 and WG200 models, where it supports the differential carrier and final drive planetary sets. The housing also integrates with the WG150 and WG250 variants when used with specific axle tube adapters. For precise fitment, verify the housing casting number against your transmission serial plate.
