ZF 4472.239.213 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 4472.239.213 REAR AXLE HOUS. is a critical structural component engineered to encase and protect the differential and final drive gearset in heavy-duty construction machinery transmissions. As an OEM genuine part, this housing ensures precise alignment of axle shafts and bearings under extreme torque loads. The SKU 4472.239.213 is specifically designed to integrate with the rear section of the transmission assembly, providing a sealed environment that maintains lubricant integrity while withstanding high-impact operational stresses. When paired with the 2094101017: TRANSMISSION HOUSING, it forms the backbone of the drivetrain’s load-bearing architecture.

Symptoms of Failure

• Hydraulic oil seepage from rear axle seals: Cracks or porosity in the housing casting often cause gradual fluid loss, leading to low lubricant levels and eventual gear damage.
• Abnormal whining or grinding noises during turns: Distortion of the housing bore misaligns differential bearings, generating metallic contact sounds under load.
• Vibration through the chassis at low speeds: Worn mounting flanges or bolt hole elongation allows the housing to shift, creating driveline oscillations.
• Contaminated transmission fluid with metallic debris: Internal fractures release particles from bearing races or gear teeth into the oil sump.

Technical Specifications

Compatibility

This rear axle housing is primarily compatible with ZF WG180, WG200, and WG250 series power shift transmissions used in wheel loaders, graders, and dump trucks. It also fits select models of the ZF 4WG-200 and 6WG-200 drivelines. For complete assembly, this housing must be mated with the 2094301069: HOUSING and the 2094298054: HOUSING to form the central casing cluster. Secure sealing is achieved using the 0636302008: SCREW PLUG for drain ports.
