Toe-In Curve Adjustment: Notes

WARNING: This page is about a different car, the 2004 Audi S4, 2004 Audi A4, 2003 Audi A4, and 2002 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before attempting any adjustments, see PRELIMINARY CHECKS and WHEEL ALIGNMENT PROCEDURES .

NOTE: An incorrectly adjusted toe-in curve adjustment causes the vehicle to pull to one side when braking or accelerating or when driving over bumps. Toe-in curve adjustment can also be referred to as toe constant "S" adjustment.

When the front wheels compress or rebound, the wheel's toe changes as a function of the compression and rebound travel. The resulting values are called toe-in curve. The wheel alignment computer determines the toe constant "S" from a value measured in initial position and a value measured in raised position. In the process it compares actual values with specified values and displays them on the screen.

Toe-in curve is adjusted when vehicle is in a raised position, by vertical adjustment of the tie-rod end. Different adapters are needed for lifting, depending on suspension variation. To prepare vehicle for checking toe-in curve adjustment, place vehicle in initial position. See BRINGING VEHICLE INTO INITIAL POSITION FOR ALIGNMENT (SUSPENSION VARIATIONS 1BA, 1BD, 1BE, 1BR & 1BV) .
