Overview
The ZF 4657.298.104 HOUSING REAR SECTION is a critical structural component designed for the WG190 and WG210 series transmissions. This OEM genuine part forms the aft enclosure of the transmission casing, housing the output shaft assembly and supporting the rear bearing system. It ensures precise alignment of internal rotating elements while containing transmission fluid under pressure. The SKU 4657.298.104 is manufactured to ZF’s exacting tolerances, providing a sealed environment that prevents contamination ingress and maintains hydraulic integrity. This rear section integrates directly with the 4657101079: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to form the complete transmission casing assembly.
Symptoms of Failure
- Rear seal oil leakage: A worn housing rear section often causes fluid weeping from the output shaft area, leading to low transmission fluid levels and eventual gear slippage.
- Abnormal driveline vibration: When the housing distorts or its mounting surfaces degrade, the output shaft loses concentricity, producing noticeable vibrations during acceleration or deceleration.
- Bearing noise from transmission rear: A failing rear housing can no longer properly support the output bearing, resulting in a distinct whining or grinding sound that intensifies with vehicle speed.
- Intermittent gear engagement failure: Misalignment caused by a compromised housing rear section prevents the shift mechanism from fully engaging gears, causing delayed or harsh shifting.

Frequently Asked Questions
Q: Can the 4657.298.104 housing be used on a WG210 transmission with a different bellhousing?
A: Yes, this rear section is universal across WG190 and WG210 platforms, but you must use the correct 4657201166: HOUS.FRONT SECT to match your specific bellhousing pattern.
Q: What torque specification should I use for the housing bolts?
A: ZF recommends 45 Nm (33 ft-lbs) for the M10 cap screws like 0636100801: CAP SCREW, applied in a crosswise pattern. Always use new 0631306816: CYLINDRICAL PIN for alignment.
Q: How do I identify if my transmission needs the 4657.298.104 or the 4657201169 rear housing?
A: Check the casting number near the output flange. The 4657.298.104 has an additional oil return port, while the 4657201169: HOUSING REAR PART is a solid casting without this feature.
