SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FDAB is.Measure the wheel alignment with the vehicle parked on level
--’
ground.The rear suspension and wheels should be inspected for
wear’or damage and repaired prior to measurement of wheel,
alignment.
TOE-IN
(1) Measure the toe-in with a toe-in gauge.
Standard value:
3.6f3 mm (.14+ .I18 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.
NOTEMake the adjustment by moving the left and the right bolts
r;hr
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”33’f30’(2) If the camber is not within the standard value, adjust it by
moving the mounting bolt located on the crossmember
side of the upper arm.
NOTEMovement of one division on the scale will cause camber
variation of about 15’.
Caution
1. As toe-in will vary 0.9 mm
(.035 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’.
