Overview
The ZF 4472.239.184 HOUSING REAR PART is a critical structural component designed for the WG190, WG210, and WG230 series transmissions. This OEM genuine part encloses the rear section of the gear train, providing essential support for the output shaft assembly and maintaining precise alignment of internal components. As a rear housing, it also serves as the mounting point for the transmission’s rear bearing and oil seal, ensuring that lubricant remains contained under high torque conditions. The SKU 4472.239.184 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units in heavy-duty industrial applications.
Symptoms of Failure
- Rear oil seal leakage: A worn or cracked 4472.239.184 housing often leads to transmission fluid seeping from the rear output area, visible as drips or wet spots under the vehicle.
- Output shaft misalignment: If the housing develops stress fractures, the output shaft may wobble or vibrate during operation, causing gear engagement issues and premature bearing wear.
- Unusual rear-end noise: A failing rear housing can produce a distinct grinding or humming sound from the transmission’s tail section, especially under load or during deceleration.
- Gear slipping or delayed engagement: When the housing no longer holds the rear bearing securely, gear train alignment shifts, leading to intermittent slipping or hesitation when shifting into forward or reverse.

Compatibility
This housing rear part is engineered for ZF’s WG series transmissions, specifically the WG180, WG190, WG200, WG210, and WG230 models. It is also compatible with certain variants of the WG150 and WG160 series when used with the appropriate adapter kit. Always verify the transmission serial number against the OEM parts catalog before installation.
During replacement, the 4472.239.184 housing integrates directly with the 4657101051: TRANSMISSION HOUSING and the 4657201151: HOUS.FRONT SECT to form the complete transmission casing. For proper alignment, the 0631306816: CYLINDRICAL PIN is used to locate the rear housing precisely during assembly. In some rebuilds, an alternative 4657201103: HOUSING REAR PART may be specified for earlier production runs.

Frequently Asked Questions
Q: Can the 4472.239.184 housing be repaired if it has a small crack?
A: ZF does not recommend repairing cast aluminum housings. Even minor cracks can propagate under thermal cycling and load, leading to sudden failure. Replacement with a new OEM part is the safest course of action.
Q: Is this rear housing compatible with the WG230 series without modifications?
A: Yes, the 4472.239.184 is a direct fit for the WG230 series. However, you must also replace the rear oil seal and gasket during installation to prevent leaks.
Q: What torque specification should I use for the cap screws that secure this housing?
A: For the M10 cap screws (part 0636100801), ZF specifies a torque of 45 Nm (33 ft-lbs) applied in a crosswise pattern. Always consult the service manual for your specific transmission model.
