REAR SUSPENSION <AWD>- Service Adjustment Procedures34-23
12AOO83
12A0081
SERVICE ADJUSTMENT. PROCEDURES
REAR WHEEL ALIGNMENT INSPECTION mm
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of wheel alignment.
TOE-IN
(1) Measure the toe-in with a toe-in gauge.
Standard value:
3+3 mm (.12+.12 in.)
(2) If the toe-in is not within the standard value, adjust it by moving the mounting bolts located on the crossmember
side of the trailing arm.
NOTE
Make the adjustment by moving the left and the right bolts
equally.
Movement of one division on the scale will cause toe-in
variation of about 2 mm
(.08 in.).
CAMBER
(1) Measure the camber with a camber/caster/kingpin gauge.
Standard value:
-1”OO’f30’
(2) If the camber is not within the standard value, adjust it bymoving the mounting bolt located on the crossmember
side of the upper arm.
NOTE
Movement of one division on the scale will cause camber
variation of about 15’.
Caution
1. As toe-in will vary 0.9 mm LO35 in.) for every
camber scale adjustment, adjust the toe after
adjusting camber.
2. The difference between the left and the right camber shall be less than 15’.

16. REMOVAL OF REAR SUSPENSION ASSEMBLY
(1) Supporting the rear suspension assembly with a trans-
mission jack, move it toward the rear (in the direction of
the fuel tank).
(2)
Graduallyibwer the transmission jack, avoiding contact
with the stabilizer bar and the propeller shaft.
Caution
1. Ensure that the propeller shaft does not bend
greatly.
2.Ensure that the liibro joint does not receive any
shock.
NOTE
The lowering of the rear suspension assembly from the
transmission jack requires three individuals due to the
amount of weight being handled (one on the differen-
tial, and one on either side of the lower arm).
(3) In order to protect the rear suspension assembly dust shield, support the lower arm ball joint with a wooden
block.
