(b) If necessary, check and adjust the On-the-car balance.
Imbalance after adjustment: 5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the axle bearing backlash.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS

2: Rear measuring point
Measure from the ground to the center of the lower suspension
arm No.2 mounting bolt.
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specification.
If the vehicle height is not within the specification, try adjust it
by pushing down on or lifting the body.
2. INSTALL CAMBER- CASTER- KINGPIN GAUGE

camber and caster have been correctly adjusted, recheck the
steering knuckle and front wheel for bearing or looseness.

(c) Turn the left and right rack ends an equal amount to adjust
the toe-in.
HINT:

Make sure that the lengths of the left and right rack ends
are the same.

Try to adjust the toe-in to the center value.
Rack end length difference:
1.5 mm (0.059 in.) or less
(d) Tighten the tie rod end lock nut.
Torque: 56 N´m (570 kgf´cm, 41 ft´lbf)
(e) Place the boot on the seat and clip it.
HINT:
Make sure that the boots are not twisted.
7. INSPECT WHEEL ANGLE
Turn the steering wheel fully and measure the turning angle.
2JZ-GE2JZ-GTE
Inside wheel35°00' (33°00' - 36°00')
35° (33° - 36°)34°55' (33°55' - 36°55')

(30.75°)30°35'
(30.58°)
If the wheel angle are not within the specifications, check to see
if the lengths of the left and right rack ends 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.
