Is it where the shaft goes into the rear housing? If it is, then a seal, would be all you need. If the seal is being replaced, most replace the circlip at the same time. While your at it, you should grease your drive shaft teeth since you're already there.
I can head East or West, it doesn't matter as long as it's on 2 wheels.
