yes my cv axles had to be replace cause of the same thing but when you replace one side you need to do the other side at the same time cause when 1 goes bad the other is not that far behind . i know from experience

I take a shoot here you can try this. try pulling the fuse or fuses that go to your heater blower and heater controls. If it stops check your heater blower it may be going bad, if you find nothing there, leave the blower unplugged and try turning your key on and see if you still hear it. If so I would think that the heater control is mess up and open and close the air blend door or you may have a wire shorted out under the dash some where.

It does sound like one of the universal joints. If you can raise the back end off the ground engage gear and the faulty u/v joint will make the wheel jump. This will let you know which side it is

there is a hub and a bearing assembly...usually you need to press the bearings into that hub...need a press to push out the old and press in the new...i replaced mine last year by going to the junkyard and taking out the hub and bearing assembly and just putting the whole thing into my car...much simpler..plus you learn how it goes together by taking it out in the boneyard..no press needed...plus if its genuine honda parts from a honda..(you can match the markings) its likely to be a very good part for a long time. Being used isn't always a bad thing as far as honda parts are concerned.This is from my own experience hope this helps you.
