Overview
The ZF 2093.117.007 REAR AXLE HOUS. is a structural core component engineered for heavy-duty construction machinery drivelines. This OEM genuine part encases the differential assembly and axle shafts, providing precise alignment and protection against extreme torsional loads and debris ingress. As the primary load-bearing shell in the rear axle system, it directly supports the 2093109001: DIFFERENTIAL and the 2093209095: DIFFERENTIAL assemblies. The SKU 2093.117.007 is precision-cast to maintain critical bearing bores and seal surfaces, ensuring long-term reliability in demanding off-road environments.
Symptoms of Failure
- Oil seepage at axle tube welds: Cracks or porosity in the housing cause gear oil to weep onto brake components, leading to reduced braking efficiency and visible drips after operation.
- Abnormal whining or clunking from the rear axle: A warped or cracked housing misaligns the 0750117075: TAPER ROLLER BEARING seats, generating rhythmic noise during turns or under load.
- Premature differential bearing failure: Distorted housing bores accelerate wear on the 2093309071: DIFF.HOUSING mating surfaces, causing metal debris in the lubricant.
- Wheel end play exceeding specification: Housing deformation at the spindle mounts allows excessive lateral movement, detectable during routine chassis inspections.

Compatibility
This rear axle housing is designed for ZF WG180, WG200, and WG250 series power shift transmissions commonly used in wheel loaders, graders, and telehandlers. It integrates with the 2093109001: DIFFERENTIAL and 2093209095: DIFFERENTIAL units found in ZF 4WG-180 and 4WG-200 drivelines. Always verify axle flange bolt patterns and carrier bearing spread before installation.

Frequently Asked Questions
Q: Can the ZF 2093.117.007 housing be repaired if cracked?
A: Welding is not recommended due to the ductile iron’s heat-affected zone embrittlement. Replacement with the OEM genuine part is the only reliable solution for construction machinery subjected to cyclic loading.
Q: What torque specification applies to the housing-to-transmission bolts?
A: ZF specifies 280 Nm (207 ft-lbs) for M16 grade 10.9 bolts, applied in a cross-torque sequence. Always use new lock washers when installing the 2093.117.007.
Q: How do I confirm this housing fits my ZF WG200 transmission?
A: Measure the carrier bearing spread (standard: 410 mm) and verify the axle tube diameter. The 2093.117.007 is compatible with all WG200 series rear axles produced after 2008.
