RE: strange road noise from my 'rocco

["Crane, Damien" <d3c@TENNANTCO.com>]

If it is a wheel bearing problem, it should be load sensitive, that is if
you turn away from the corner with the problem, it will load that side of
the suspension and the noise should be worse.  Conversely, if you turn in
the direction of the corner with the problem, it will unload that side and
the noise should diminish.
