Pin hole in CV boot?

Don't think it was a pinhole in the CV boot, was completely dry and clean when I checked it. Anyone know what color the front wheel bearing grease is from the factory? (2001 Forester)

If it were front wheel grease, you would see some evidence of it coming out around the hub and on the inside of the wheel/tire. If, as you say, it is all along the whole length of the underside of the vehicle, then I would guess it came from something on the road. I don't know about your Forester, but the last couple Subies front wheels I have worked on have had cassette bearings (two in each wheel) and they just don't contain very much grease, not enough to spread very much on the underside of the vehicle.

Just took it out for a spin to see if I could find any more traces or source for grease - did a tweny mile jaunt at high speed, did several sharp turns, no trace of any more mystery blue grease. CV boot, suspension, inside of wheel are clean, no noises or vibrations. Leads me to believe that it was something I picked up on the road. Will still keep an eye on it, would rather err on the side of caution.

Dan,

I have a lot of highway construction going on around my neighborhood, and they are pouring concrete for curbs etc. They grease their forms to keep the concrete from sticking, and also tend to overgrease their construction equipment. Needless to say, I've had grease in my wheelwells and all down the side of my WRX. Quite nasty. Blue grease suggests waterproof grease.
