ZF 5838.117.033 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.117.033 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 mounting point for the wheel hubs and absorbing all torsional and vertical loads from the drivetrain. As the primary casing for the rear axle system, it ensures precise alignment of internal gears and bearings. The SKU 5838.117.033 is engineered to withstand extreme shock loads common in excavators and wheel loaders, directly supporting the 5838109023: DIFFERENTIAL assembly and the 2095209037: DIFFERENTIAL unit within the housing.

Symptoms of Failure

• Oil seepage from axle tube welds or casting pores: Cracks or porosity in the housing allow gear oil to escape, leading to low lubricant levels and accelerated wear on internal components.
• Excessive driveline backlash or clunking: A warped or cracked housing cannot maintain proper bearing preload, causing the 0750117075: TAPER ROLLER BEARING seats to shift, resulting in audible play during direction changes.
• Uneven tire wear or wheel misalignment: Structural deformation of the housing alters the axle geometry, causing chronic misalignment that cannot be corrected by standard suspension adjustments.
• Metallic debris in differential oil: Internal fractures in the housing can grind against the 2095309059: DIFF.HOUSING, shedding metal particles into the lubricant.

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, as well as the WG160 series in certain loader configurations. The housing also integrates with the HP90 and HP100 final drive modules. Always verify the axle ratio and brake configuration before installation.
