The driver's side front wheel bearing on my FC seems to be seeping grease. Every time I pull that wheel there is bearing grease on the inside of the wheel bore (where the centering ring is).

It's not a huge amount, but it's like that wheel bearing is maybe getting really hot and the grease seeps out from the grease cap. I haven't pulled the hub yet...I have an event this weekend and don't want to be down. Should I be concerned? The pax side is just fine, nice and dry. The grease cap isn't damaged either - that's the first thing I checked.

 

yeah, more then likely you over heated the grease... pull them apart, clean them up and repack them with a quality hi temp wheelbearing grease before you burn up a wheel bearing(which you may already have done)
