Overview
The ZF 4472.239.214 REAR AXLE HOUS. is a critical structural component engineered to encase and protect the final drive gearing within ZF heavy-duty construction machinery transmissions. This OEM genuine part serves as the primary load-bearing shell for the rear axle assembly, ensuring precise alignment of differential gears and bearings under extreme torque conditions. The SKU 4472.239.214 is specifically designed to withstand high axial and radial forces encountered in earthmoving equipment, wheel loaders, and graders. When installed alongside the 2094101018: TRANSMISSION HOUSING, it forms a sealed unit that prevents contamination from debris while maintaining optimal lubricant flow to the gearset.
Symptoms of Failure
- Hydraulic oil seepage from axle housing seams – Visible fluid accumulation around the housing mating surfaces indicates gasket degradation or micro-cracks in the casting, often triggered by thermal cycling in heavy-load operations.
- Abnormal whining or grinding during turns – Worn bearing seats inside the housing cause differential gear misalignment, producing metallic noises that intensify under load during low-speed maneuvering.
- Increased backlash in driveline – A loose or cracked housing allows the ring gear to shift, creating a noticeable clunk when shifting between forward and reverse gears in construction machinery.
- Contaminated transmission fluid with metallic particles – Internal fractures in the housing release debris into the oil system, detectable during routine filter inspections or oil analysis.

Compatibility
This rear axle housing is primarily utilized in ZF WG180, WG200, and WG310 series power shift transmissions commonly installed in construction machinery such as wheel loaders, dozers, and telehandlers. It also fits select variants of the ZF 4WG-200 and 6WG-200 drivetrains. For proper sealing, always pair this housing with the 2094301069: HOUSING and the 2094298054: HOUSING component. The 2094301071: COVER must be installed to complete the axle assembly and prevent lubricant loss.
