CHECKING AND ADJUSTING SEQUENCE-FRONT
WHEEL ALIGNMENT
All measurements and adjustments should be made in the
following order.
a. Curb weight and height (see Curb Height chart in
Section 0).
b. Caster and camber.
c. Cross.
ADJUST CASTER AND CAMBER
Caster and camber are adjusted to specifications by plac-
ing shims between the upper control arm shaft and the
frame support (Fig. 3-17). Both adjustments can be made
at the same time. In order to remove or install shims,
loosen the control arm shaft to frame support bolts. Tool
J 22618 can be used to loosen upper control arm shaft to
frame support bolts on the B Series (Fig. 3-18).
NOTE:
A
shim pack should not exceed 3/4
inch maximum, with a maximum difference of
3/8
inch between front and rear shim packs.
To increase negative caster add shims to front bolt or
remove shims from rear bolt.
To decrease negative caster (increase positive caster)
remove shims from front bolt or add shims to rear
bolt.
To increase positive camber remove shims from both
front and rear bolts.
To decrease positive camber (increase negative cam-
ber) add shims to both front and rear bolts.
NOTE: By adding or subtracting an equal
amount of shims from front and rear bolts,
camber will be changed without affecting
caster.
