from the front or rear steering gear or after adjusting
the wheel alignement, or if the rear steering angle is
not correct, adjust the rear turning angle as described
below.
Warning
Improper installation of the 4WS steering
transfer shaft may affect control of the vehi-
cle and result in the risk of an accident or per-
sonal injury.

shaft to align the notch in the input shaft with the
center of hole.
5. Remove the set bolt attached to the rear steering
gear, and install it in the steering gear to set the
input shaft.
Tightening torque:
4.9—7.8 N-m (50—80 cm-kg, 43—69 in-lb)
86U10X-314
Note
After the input shaft is set, manually turn the rear
joint and chack that the shaft does not move.
