Yeah I wish it was something like the sway bar link. That's not my luck.
I had searched through the archives and I did find at least one person who had a grinding sound and it ended up being the wheel bearing. It just seems that it usually is a humming noise. Searching through the net at large, if it is the wheel bearing and it is making a grinding noise, I need it fixed now, not later.
"A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)"
Yeah, that's not cool.
