ZF 5838.117.001 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.117.001 REAR AXLE HOUS. is a structural core component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encloses the differential and axle shafts, providing the rigid mounting point for wheel ends and absorbing extreme torsional loads during operation. As the primary load-bearing casing, it directly supports the 5838022003: REAR AXLE assembly and houses the 5838109001: DIFFERENTIAL unit. The SKU 5838.117.001 is precision-machined to maintain exact gear mesh alignment, ensuring consistent power transfer from the transmission to the wheels under high-stress excavation and material handling conditions.

Symptoms of Failure

• Hydraulic oil seepage from axle housing seals: When the housing develops micro-fractures or the mating surfaces warp, you will notice gear oil pooling around the hub flanges or dripping from the housing drain plug area.
• Abnormal whining or grinding noise during turns: A cracked or distorted rear axle housing allows the differential carrier to shift, causing the 0750117075: TAPER ROLLER BEARING to wear unevenly, producing a distinct low-frequency growl under load.
• Premature tire wear and tracking issues: A bent housing alters the wheelbase geometry, leading to uneven tire scrubbing on one side and a constant steering pull during straight-line travel.
• Metal debris in differential oil: Housing fatigue can cause the 5838300128: DIFFERENTIAL HOUSING to contact rotating gears, generating metallic particles that contaminate the lubricant.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF’s heavy-duty powershift transmission series commonly deployed in wheel loaders, telehandlers, and graders. It is a direct fit for the following ZF transmission models: WG180, WG200, WG210, and WG250. The housing is also compatible with certain variants of the 4WG-200 and 4WG-210 series used in construction machinery from manufacturers such as Volvo, Liebherr, and JCB. Always verify the axle ratio and housing bolt pattern against your existing unit before installation.
