After replacing my front brake pads and rotors about 6 weeks ago (got
105K miles out of the factory pads) I suddenly began hearing a
metal-on-metal scraping noise from the driver's side front wheel.  It
sounded like the thin metal sheild behind the wheel was rubbing, but it
is not.
I did some experimenting, and found that when I lock that hub, the
noise goes away.  Unlock it, and it comes back.  Doesn't matter if I'm
truly in 4wd or not, but when the hub is in the "Free" position, the
screeching noise is unbearable.
It's clearly related to the speed of the revolution of the wheel, but
not 100%.  That is, it doesn't just squeal once for each revolution.
It could be once, three times, or it could go for a few blocks without
any screeching at all.
Do I just need to pull that hub apart and see what the problem is?
With 106K miles, should I consider buying aftermarket hubs and
replacing both factory hubs?  If so, any recommendations on a
brand/source for these?  Thanks in advance.
