Overview
The ZF 4469.315.006 BUSH is a precision-engineered plain bearing component designed for the planetary gearset support structure within the WG 200 series transmissions. This OEM genuine part, identified by SKU 4469.315.006, functions as a sacrificial wear surface that reduces friction between the rotating shaft and the stationary housing assembly. It is specifically positioned within the output shaft region of the transmission, where it absorbs radial loads and maintains concentric alignment of the rotating elements. The bushing works in direct conjunction with the 4460115043: HOUSING to provide a stable bearing surface, ensuring that the shaft does not contact the housing directly during high-torque operations.
Symptoms of Failure
When the ZF 4469.315.006 BUSH wears beyond tolerance, operators will notice distinct performance degradation. The most common failure symptom is a low-frequency “rumble” or vibration emanating from the transmission casing during acceleration, indicating excessive clearance between the bushing and the shaft. A second critical sign is metallic debris present in the transmission fluid during routine oil sampling, which points to the bushing material breaking down. Third, you may observe intermittent gear engagement hesitation or a “clunk” when shifting between forward and reverse, caused by the shaft shifting laterally within the worn bushing. Finally, oil seepage around the output flange area often occurs because the misaligned shaft compromises the adjacent 0734319337: SHAFT SEAL.

Compatibility
This bushing is engineered specifically for the ZF WG 200 series transmission family, which includes the WG180, WG200, and WG210 models. It is also compatible with certain variants of the ZF Ecomat 4HP and 5HP series that share the same planetary carrier architecture. The part is designed to interface directly with the 4469315012: AXLE DRIVE HOUSING and supports the shaft assembly that rides on the 0750117406: TAPER ROLLER BEARING and the 0750117802: TAPERED ROLLER BEARING. Always verify your transmission serial number against the ZF parts catalog before ordering.
