Greasing new wheel bearings and hub.

I always put some in the hub void,as well as the cap. Thats how i find them, and i put them back that way. Its a mess when a bearing fails, makes more work to clean up.
Bearings fail for only 3 reasons. too tight
Too loose
Contamination

Not like the conventional unitized hub/bearings. They just fail.
