Why?
What going to be the big difference if you use the new race that's currently in the rotor, and the new bearing that your talking about?
Never going to notice anything detrimental with the bearings being packed with grease.
If I knew the answer to that question I might not be taking the ones that came with the rotors out.
Believe me I'd just throw it in there if it was a trailer, but I want the new races that came with the new bearings in there.
Keep in mind that I asked opinions on taking the existing ones out being there is no access to them, and not weather I should or not.:D
