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')
34.92° (32.92° - 35.92°)
Outside wheel
30°45'
(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.
