I am trying to wrap up my front wheel bearing job and have a couple lube questions.

The factory bearings had lost some grease onto the aluminum hub through the split in the bearing race. That or the hubs were greased from the factory. The question is, should I apply some grease to the aluminum hub where the inner bearing race sits?

The splines were greasy from the factory too, but no mention in the manual. Do I regrease the splines?
