hello all, just doing the first service on my kodiak, and upon draining the rear diff oil i noticed i loosened the drain bolt further up towards the engine(not the engine, its still on the rear diff) and theres another drain bolt right under the back of the diff where the axles go into the housing, did i just drain something different than diff oil or does the rear diff just have 2 drain plugs? thanks and sorry for the dumb question. Im use to working on old junk bikes lol
