I am pretty sure your final drive and bearings will be fine.Your not the first or the last to have the low oil problem there.When I first got my 6 I saw on the Goldwing site that this was a common problem with most dealers and posted here that it would be wise to check the level.As far as calling Honda like the famous paint problems they will most likely do nothing.And if one does need warrenty work a lot of dealers have techs I would not want touching my baby with a ten foot pole.Best thing a Wing owner can do is check the forums as most give good advice,get Fred's DVD set and some good tools.Nice thing is these are pretty low maintanence scoots and go many trouble free miles-Plus as said before with trike take off parts E bay is your friend.If you need a black rear end I got one on the shelf in the packing box as it was 100.00 to my door-With luck I will need it in a 120 thousand miles or so.
