How does the pinion shaft affect the oil seal?
With the pinion shaft being surrounded by the seal, small lips on the seal face the inside of the differential, so any oil that makes it past the oil slinger (a small disc in front of the seal) will only slide up the oil seal, not under it. This causes the oil to return to the differential case instead of flowing between the seal and pinion shaft.
