lAll dimensions indicated in figures are actual ones.
lWhen using a tracking gauge, adjust both pointers to equal length. Make sure there is no free play.
lWhen a measuring tape is used, check to be sure there is no elongation, twisting or bending.
lMeasurements should be taken at the center of the mounting holes.
lAll measurements and mounting hole diameters are expressed in millimeters (mm).
lAn asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
lThe coordinates of the measurement points are the distances measured from the respective dimension
lines in the directions of ``x'', ``y'' and ``z''.
Dimension lines: ``x'' line Ð Center line of vehicle
``y'' line Ð Center line of front axle (Any measurement point in front of the dimension
line refers to a minus ``Ð'' value.)
``z'' line Ð Datum line (Any measurement point under the dimension line refers to a
minus ``Ð'' value.)
