Overview
The ZF 5838.117.028 REAR AXLE HOUS. is a critical structural component designed to encase and protect the differential and final drive gearset within heavy-duty construction machinery transmissions. As an OEM genuine part, this housing serves as the rigid backbone that supports axle shafts and maintains precise gear alignment under extreme torque loads. The SKU 5838.117.028 is specifically engineered for ZF’s powershift transmission series, where it absorbs torsional stress and prevents contamination from entering the drivetrain. When paired with a 5838109019: DIFFERENTIAL, this housing ensures optimal load distribution across the rear axle assembly.
Symptoms of Failure
- Persistent gear oil seepage from axle seals: A cracked or warped rear axle housing often manifests as slow, steady oil drips pooling beneath the differential area, especially after prolonged operation in construction sites.
- Abnormal whining or grinding during turns: When the housing loses structural integrity, misalignment forces the 0750117075: TAPER ROLLER BEARING to wear unevenly, producing metallic chatter during low-speed maneuvers.
- Recurring differential bearing failures: A distorted housing causes repeated premature failure of the 2093209024: DIFFERENTIAL carrier bearings, requiring frequent rebuilds every 500-800 operating hours.
- Visible hairline fractures near mounting flanges: Stress cracks typically develop around bolt holes, allowing debris ingress that accelerates internal gear wear and necessitates immediate replacement.

Compatibility
This rear axle housing is precision-machined for ZF WG180, WG200, and WG211 powershift transmission families commonly deployed in wheel loaders, graders, and heavy forklifts. It directly interfaces with the 0631329088: SPRING PIN used to secure the differential carrier. The housing also accommodates final drive ratios ranging from 4.8:1 to 6.2:1. Verify your transmission serial number against ZF’s OEM cross-reference to confirm fitment for models like the WG180-5 or WG200-3 series.
