(1) I had a steel belt let go on a Ford Explorer (wife's vehicle) -- what a trip that was... it went on for weeks and got progressively worse -- initially, it was just a tap-tap-tap noise that would come and go depending on speed, however, apparently as more and more of the belt ruptured the vibration got worse and worse to the point that you could not go more than 25mph without it shaking the entire vehicle as if one side of the vehicle was on a normal road and the other side was on a "pot hole test track"... the amazing
thing was that the bad tire was actually on the opposite side of where the dirver thought the issue was (!!!). Anyway, if this is the issue in your case, just jack up every wheel, in turn, and run your hand over the tread surface -- if you feel a slight bubble (on the treaded surface), then you may have a rupturing steel belt.
(2) My own 02 Conv (2wd) does have adjustable
wheel bearings in the front (the non-driven axle) and I experienced something similar at about the 100K mark -- a minor effort to re-adjust them.
: a rupturing steel belt will be most noticeable at lower speeds and largely disappear at higher speeds; a bad wheel bearing will normally not be noticeable at lower speeds, but rather btwn 45mph and 65mph in the form of a slight noise/vibration intitially, then a more pronounced squeeling and vibration toward the end.
