Front axle toe-in curve, adjusting
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
Explanation:
When the wheel compresses or rebounds, the wheel s toe changes as a function of the compression and rebound travel. The resulting toe measurements are described as the toe curve.
The change in the toe constants "S" is adjusted when the vehicle is raised by vertically shifting the tie rod end → Toe constant "S" , adjusting
The wheel alignment computer determines the toe constant "S" using values measured in the initial and raised positions. The computer compares the measured values with the specifications and displays them on the screen.
Depending on the suspension, various adapters are necessary for raising the vehicle → Application of adapters to suspension for measurement .
NOTE:
- An incorrectly adjusting toe constant causes vehicle to turn when braking/accelerating or when driving over bumps.
