Overview
The ZF 4657.298.107 HOUSING REAR SECTION is a critical structural component designed for the WG190, WG210, and WG230 series transmissions. This OEM genuine part forms the aft enclosure of the transmission casing, directly housing the output shaft assembly and supporting the rear bearing cluster. By containing transmission fluid and maintaining precise alignment of internal gears, the rear housing ensures torque is transferred smoothly to the driveline. The SKU 4657.298.107 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units. It integrates seamlessly with the 4657101085: TRANSMISSION HOUSING and the 4657201161: HOUS.FRONT SECT to form a complete, leak-free casing assembly.
Symptoms of Failure
- Rear main seal oil leaks: A cracked or warped rear housing section often leads to fluid weeping from the output shaft area, visible as drips under the transmission bell housing.
- Output shaft play or vibration: When the housing bore wears, the rear bearing loses support, causing excessive radial movement and driveline shudder during acceleration.
- Gear engagement difficulty: Misalignment from a damaged housing can prevent the shift rails from moving freely, resulting in hard shifting or gear clash in WG190/WG210 units.
- Contaminated transmission fluid: Cracks in the housing allow dirt and moisture ingress, which accelerates wear on internal components like the 4657201162: HOUSING REAR PART.

Frequently Asked Questions
Q: Can I use the 4657.298.107 housing on a WG230 transmission?
A: Yes, this part is OEM-approved for the WG230 series. However, you must also replace the 0631306816: CYLINDRICAL PIN to ensure correct alignment during reassembly.
Q: What is the typical lifespan of this rear housing section?
A: Under normal operating conditions, the cast aluminum housing lasts the life of the transmission. Failure usually occurs only after a bearing seizure or impact damage. Inspect for cracks whenever you service the output shaft.
Q: Do I need to replace the oil feed housing when installing this part?
A: It is strongly recommended. The 4656301047: OIL FEED.HOUSG. often suffers galling from the same wear event that damages the rear housing, so replacing both ensures proper lubrication.
