Front Wheel Suspension, Wheels and Tyres (Toe): Repair Instructions

Toe

The toe (1) is the angle determined on a stationary vehicle between the lines of intersection of the wheel centre planes (3) and the parallel geometric driving axis (2).

When the vehicle is being driven, the vehicle's wheels attempt to swivel outwards or inwards due to forces acting on them. Various forces come into play during acceleration and braking, but also at constant speeds.

The adherence to the toe values specified for Opel/Vauxhall vehicles specified ensures that the wheels have good straight-line stability (tracking stability) without any wheel wobble.

We distinguish between toe "0" (i), "positive" toe (II, toe-in) and "negative" toe (III, toe-out). Toe "0" Toe "0" is the parallel position of a wheel centre plane (1,3) to the geometric driving axis (2). "Positive" toe (toe-in) In this position, the front part of wheel is facing the geometric driving axis. "Negative" toe (toe-out) In this position, the rear part of the wheel is facing the geometric driving axis.

Individual toe

The individual toe (1) is the angle between a wheel's centre plane (3) and the geometric driving axis (2).

Total toe/track

The angle of the total toe is calculated by adding or subtracting the individual toe values for an axle.

With individual toe values with the same prefix (+/-), the values are added.

Example

If the individual toe values for an axle have a different prefix (+/-),the smaller value is subtracted from the higher value.
