place the car so that the front end is level cross-
wise and then rock the car sidewise several times
and allow the car to settle. This will remove any
binding that might cause a dimension difference.
Measure the distance from the top of this lower
support arm to the bottom of the upper rebound
bracket, which should be 4-5/32" each side. (Curb
load without passengers.) Shown at "B", Figure 1,
Front Suspension.
If the two measurements vary more than 1/2"
between sides, it is advisable to replace one or both
coil springs.
NOTE: The high limit spring has Red Paint for
identification and White Paint for low limit; these
markings will be found at the bottom of the spring.
RIDING HEIGHT REAR
Front wheel alignment is affected by weak
rear springs or shock absorbers. To determine
the riding height measure the distance vertically
from the top of the rear axle housing tube to the
upper edge of the rear axle rubber bumper,
Figure 8, Front Suspension. This distance should
be 6-1/16" (Curb load - less passengers).
