Hi all,
I was changing the engine oil today and noticed some oil spray around a drive shaft:

Uploaded with
ImageShack.usThe rubber gaiter around the driveshaft seems loose, what do I need to replace here? anyone else had this problem?
also will this be gearbox oil I'm losing? If so, I will top up the oil urgently. Or is it just grease?
- I have located the top-up hole. Is there a way to check the current level?
