I would check your wheel bearings on that side just to be sure they are
OK.  Jack up the van on that side and then try to move the tire.  Grab
the tire at the 12 oclock and 6 oclock positions and try to cock it from
side to side.  It should not have any play in it.  If it moves  (has
play in it) then the bearings are bad and should be replaced.

Hope this helps.
