I had a chat with Jason and he immediately said it was grease from the rubber boots/gaitors that must have cracked/rotted/perished, and needed replacing.
As I needed to pop down to Singapore I asked him to replace all of them, as I presumed they'd all be pretty grotty. So he got 4 new ones, two for the engine end and two for the wheel end.
Anyway, as you can see, the passenger side one was pretty shot.

Here's the grease that was being thrown on to the caliper and the inside of my lovely wheel.

So, like i said, he put on four brand spanking new ones and plenty of grease back onto the drive things.

So, it's goodbye to greasy wheel misery and hello smooth running front end.
