Oil leakage due to inadequate support of the reaction sun gear.
The Sonnax sun gear bushing is more than one-and-a-half times as wide as the OEM and maximizes bushing support.
The Sonnax replacement bushing 77010-01 is one-and-a-half times the width of the OE version and fills the entire sun gear bushing groove. This wider bushing maximizes support. The bushing is steel-backed bronze that is precision machined to provide minimal clearance with the mating shaft.
