b. Correction of Trim
When the trim dimension is found to be too
low, correction may be made by insta'Iing spe-
cial shims (group 7.425),
Ys"
thick, between
upper end of spring and the frame.
If
more
than three shims are required, replace the
spring.
c. Use of Optional High or Export Springs
For special requirements where excessive
bottoming occurs on regular springs with nor-
mal loads, it is advisable to install optional high
or export
springs,
which are slightly longer
than the regular springs. Front shock absorber
calibrations need not be changed upon installa-
tion of optional high or export front springs.

1.
Place jack under lower control arm, raise
wheel off floor, and remove wheel and tire as-
sembly.

trol arm and disconnect outer end of tie rod
from steering arm.
3. Remove lower pivot pin nut, pivot pin,
lockwasher, and dirt seals.

part number which is stamped on one end coil
to make sure that spring is correct for the car
model
,

spring insulator is in place around the spring
center cup on frame, and is in good condition.
2. Place small end coil of spring over the
center cup and as lower control arm is raised,
position lower end of spring so that the end
coil seats in the recess provided in spring seat.
