One deflector is located in the lower portion of the carrier adjacent to the outboard pinion bearing and is angled to direct the flow of lubricant toward the inboard pinion bearing, while another deflector is in the upper portion of the carrier adjacent to the inboard pinion bearing and is angled to direct the flow of lubricant toward the outboard pinion bearing. The carrier lubricant is thereby directed along a generally one-way fluid path, minimizing the direct recirculation of high temperature oil through the outboard pinion bearing. | |
