GENERAL INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and for the proper inflation pressure.

Measuring point:
Measure from the ground to the center of the lower suspen-
sion arm front mounting bolt.
NOTICE: Before inspecting the wheel alignment, adjust
the vehicle height to specification.
If the vehicle height is not to specification, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER±CASTER±KINGPIN GAUGE OR
ONTO WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufactur-
er.

If the steering axis inclination is not as specified, after camber
and caster have been correctly adjusted, recheck the steer-
ing knuckle front wheel for bearing or looseness.
4. INSPECT TOE±IN
Toe±in (total):
A+B: 0° + 0.2°
C±D: 0 + 2 mm (0 + 0.08 in.)
If toe±in is not within specification adjust by the tie rod end. SA±4

5. ADJUST CAMBER AND CASTER
(a) Remove the engine under cover.
(b) Remove the nut, 2 bolts and front lower arm bracket stay.
(c) Loosen the front and/or rear adjusting cam nuts.
(d) Adjust the camber and caster by front and/or rear adjusting
cams. (See adjustment chart)

Bolt: 59 NVm (600 kgfVcm, 43 ftVlbf)
(g) Install the engine under cover.
6. ADJUST TOE±IN
(a) Remove the boot clamps.
(b) Loosen the tie rod end lock nuts.
(c) Turn the left and right tie rod ends an amount to adjust the
toe±in.
Toe±in (total):
A+ B: 0° + 0.1°
C±D: 0 + 1 mm (0 + 0.04 in.)
HINT: Ensure that the lengths of the left and right tie rods are
the same.
Tie rod end length left±right error:
Less than 1.5 mm (0.059 in.)
(d) Tighten the tie rod end lock nut.
Torque: 56 NVm (570 kgfVcm, 41 ftVlbf)
(e) Place the boot on the seat and clip it.
HINT: Ensure that the boots are not twisted.

If wheel angle differ from the standard specifications, check
to see if the lengths of the left and right tie rods are the same.
HINT: If the tie rods lengths are not equal, the wheel angle
cannot be adjusted properly.
Reinspect the toe±in after adjusting the tie rods lengths. SA±6

ADJUSTMENT CHART
HOW TO READ ADJUSTMENT CART
(a) Mark on the graph the measurements taken from the vehicle.
Example (2JZ±GE):
Camber: +0°10'
Caster: +4°20'
(b) As shown in the illustration, read from the graph the amounts
by which the front and/or rear cams are to be adjusted.
Amount to turn adjusting cam (by graduation):
Front cam: + (Longer) 1.8
Rear cam: ± (Shorter) 2.2

5. ADJUST CAMBER AND TOE±IN
(a) Measure the length of the lower suspension arm No.1 and
No.2, as shown in the illustration.
Length:
(E±F) or (F±E) should be less 4.0 mm.
If not, adjust the length of the arms by turning the adjusting
cam, as shown, until (E±F) or (F±E) is less than 4.0 mm.
(b) Measure the camber and toe±in.
