The output seal of my rear housing (HF2A T-case) is leaking. I'll replace the oil seal and ball bearing, but I noticed in the FSM, the dust deflector on either side of the oil seal is a "non-reusable part". Searching other similar fixes, I see no mention of the dust deflector. Do I need to replace the two dust deflectors? Anything else I should do while I'm in there?
