1. Adjustment of Front Wheel Toe-In
The toe-in can be adjusted using an optical tester or a mechanical toe-in regulator.
1.1 On the basis of requirement of the tester, position the wheels and conduct the preparation
work before adjusting.
1.2 Loosen the lock nut and of the elastic protective sleeve snap ring right steering tie bar. Turn
the toe-in regulator lever as required to regulate the length until it reaches the specified value; and
the toe-in value: 6′±6′.
1.3 Tighten the lock nut, reinstall the elastic snap ring of protective sleeve, and then check
whether the lock nut is tightened and whether the position of protective sleeve is proper;
Torque: 35±3Nm
1.4 After adjusting toe-in of front wheel, check whether the steering wheel is horizontal.
Otherwise, loosen the lock nut of steering wheel, regulate the steering wheel to the horizontal
position, and then tighten the steering wheel lock nut to the specified torque.
2. Adjustment of Front Wheel Camber Angle
2.1 In the normal case, after the independent suspension and
wheel steering knuckle are assembled, it is unnecessary to
adjust the camber angle. If the wheel camber angle is found
deviated from the tolerance range due to the other causes,
apply the connecting bolts of independent suspension and
steering knuckle to correct the camber angle.:
Front wheel camber angle: 0.87°±50′
