There is an oil baffle, and an oil slinger.
The baffle (what I call it, may be called something else) goes behind the inner pinion race, and has a hole just larger than the pinion shaft. This keeps the oil level up a bit in the snout where the outer bearing sits.
The slinger is a large disc thats pressed between the pinion head and outer bearing. It slings oil into the passage going to the outer bearing. In a rear axle, the oil whips off of the ring gear down this passage, in the front the gear is rotating the other direction, so the slinger gets lube in there.
Think for yourself
