If you're leaking gear oil, though, your axle seal is bad and you have to replace the bearing to replace the seal (yee-haw!)
This write up is decent:

but you don't have to remove the differential cover unless you're due a fluid change anyway - but you probably already knew that since you pulled the shaft to check the bearing.
