readouts, the front and rear of vehicle should be
jounced. Induce jounce (rear first, then front) by
grasping the center of the bumper and jouncing
each end of vehicle an equal number of times. The
bumper should always be released when vehicle is
at the bottom of the jounce cycle.

  (4) Read the vehicle’s current front and rear align-
ment settings. Compare the vehicle’s current align-
ment settings to the vehicle specifications for camber,
caster and toe-in. Refer to WHEEL ALIGNMENT
