ADJUST CAMBER AND TOE–IN
(a)
Measure the lengths of the toe control link and No.2 lower
suspension arm, as shown in the illustration.
Length: A – B = 4.0 mm (0.16 in.) or less
If they are not within the specifications, adjust the lengths of
them by turning the adjusting cam, as shown, until (A – B) is less
than 4.0 mm (0.16 in.).
(b)
Measure the camber and toe–in.
(c)
Adjust the camber.
(1)
Loosen the camber adjusting cam nut of lower sus-
pension arm No.2.
(2)
Turn the camber adjusting cam of lower suspension
arm No.2 and adjust camber.
HINT:
Camber changes about 5.0’ (0.08
°
) with each graduation of the
cam.
(3)
Torque the camber adjusting cam nut.
Torque: 110 N·m (1,120 kgf·cm, 81 ft·lbf)
