Toe-in is the amount by which the front and/or rear wheels of a vehicle are turned in or out from a straight-line position. If the wheels are turned inward, the toe is positive (+). If the wheels are turned outward, the toe is negative (-). The actual toe value is only displayed when measured, as the purpose of the toe setting is to ensure that the wheels roll parallel. Toe-in compensates for small deviations in the wheel support system as the vehicle moves forward. In other words, toe-in occurs only when the car is stationary; when it is moving, the wheels are aligned parallel to each other.
Incorrect toe adjustment leads to increased tire wear and causes steering instability.
Adjusting the angle of rotation and / or convergence of the front wheels
1. Make sure that the front wheels of the vehicle are in the straight ahead position.
2. Loosen the tie rod end nut (1).
3. Adjust the toe value by turning the knob (2) (value see section «Service data and specification» at the end of the chapter).
4. Tighten the nut (1) tie rod end with a torque of 68 Nm.
Adjustment of a convergence of back wheels
1. Measure the amount of convergence of the rear wheels on a special stand.
Note. Do not overtighten new fasteners to ensure mutual movement of components.
2. By turning the cam nut shown in the figure, adjust the toe-in of the rear wheels to the required value (see section «Service data and specification» at the end of the chapter).
3. Screw on the cam bolt by hand and then tighten to 150 Nm while holding the cam nut from turning.
4. Repeat the procedure for the second rear wheel.
5. Lower the car.
