The pinion gear rotates at driveshaft speed and can mimic a driveshaft speedrelated vibration. Improper pinion bearing preload can cause what appears to be a pinion seal leak, but the seal is fine, the pinion gear is moving vertically, horizontally, or diagonally as is rotates. No seal can hold on oil under those conditions.
