A ram air turbine gearbox includes a turbine drive shaft defining a primary axis, a gear coupled to an outer surface of the drive shaft configured to transfer power from the drive shaft to a generator. A bearing is coupled to the outer surface of the drive shaft aft of the gear along the primary axis, a bearing support is positioned radially outside of the bearing configured for enclosing the bearing within a gearbox housing from an axially aft direction. A bearing liner is positioned radially between the bearing support and the bearing and a crest to crest wave spring positioned radially inside the bearing liner and axially forward of the bearing.
