TomTom,Q The tires on my 2005 Chevy pickup have been replaced and the wheels
aligned;    however,    at  60  miles   per hour    the steering    wheel   starts  to  shake.
What’s  wrong?
Walt—Burlington,    VermontWalt,A Take the truck back to the shop that replaced the tires and have them re-
check   the calibration of  the wheel   balancer    and your    tires   for proper  balance.
They    probably    got it  wrong   when    they    balanced    the new tires.  This    is
common  as  wheel   balancers   should  be  recalibrated    for every   new set of  tires
and wheels. Imbalanced  tires   cause   shaking.    If  the tires   are okay,   then    check
the steering    linkage and suspension  for worn    parts.
