Thanks Dnk, Good source of info there!
I've been out, jacked the car up to make sure the grease was emanating from where I first thought. If I pressed very hard with my hand I got a small amount of movement between the two metal casings. I tried the same on the other side but got no visible movement.
I'm probably being thick but I'm just not sure which parts on the diagrams are the outer casing of driveshaft next to the hub
So the quickest fix I can think of would be if someone has a nearside tt driveshaft. I believe as it's the short one so it has to be from a manual TT. It's got the large Diff and is a UK car. (Hopefully someone who's done this before can put me straight right here.
Thanks in advance
