Hi guys! everytime i clean my front offside alloy i notice a really greasy patch on it, and when i try to clean it it builds up more. does any1 have a clue to what this could be? leaky breaks or somethin? Ill get a pic up of it if that'll help anyone? Cheers

Sounds to me like youve got a leaky driveshaft gator fella.

^ second that, I'd get it looked at sooner rather than later. Gaiter and grease is a simple enough fix. If it all dries out, could be looking at a new drive shaft. More expensive fix.
