Need a few opinions:
Had a great track day in Laguna Seca today
After session 3 I noticed that a lot of grease was coming off the hub in the center of the right rear wheel and then got pushed by the centrifugal forces all over the rim (see attached pic).
It seems to me that the grease came out the hole in the center of the axle. Seems like the axle is hollow and connected to the CV boot.
So I now have two theories:
a) wheel bearing going bad
b) axle going bad
This does not happen in daily driving only when I'm at the track and the brakes get really hot and apparently "cook" the grease
Anyone had this happen to him before?
