Jeff:

If it is road speed related, on coast only, I'd suspect the driveline. If it sounds very much like every other wheel revolution, it can be the rear wheel bearings (they are sealed double-race ball bearings in the control arm).

Be glad it is as warm as it is there -- current temp is -2F, going as low as -5 tonight, we MAY see 18 tomorrow! Warmer than where I used to live, though -- never gets up to 0F in Sault Ste Marie, Ontario this time of year!
