Doing the brakes on the HF soon. Iam going to be swaping in a b18 soon. Was wondering if I could swap out the hubs and still use the hf axles? I don't know. The hub is the whole are piece right? And are they sealed bearings? Do they need to be pressed with a press? Just asking cause when i get the hubs i will want to go ahead and replace the bearings. Sorry if this is a stupid question but I really don't know.
