Thrust Angle (Deviation From Direction Of Travel), Calculating
WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
- If alignment readings for rear toe are both positive or both negative (+/+ or -/-), subtract the smaller figure from the larger figure to determine total toe angle, then divide by 2.
Example:
THRUST ANGLE EXAMPLE 1Toe angle of left rear wheel: + 15' Toe angle of right rear wheel: + 5' Total toe angle (+/+; subtract 5' from 15'): + 10' Thrust angle = total toe + 2: + 5' Thrust angle (deviation from direction of travel) = 5' - If alignment readings for rear toe are different signs, one positive and one negative (+/-), add the two figures to determine total toe angle, then divide by 2.
Example:
THRUST ANGLE EXAMPLE 2Toe angle of left rear wheel: + 15' Toe angle of right rear wheel: - 5' Total toe angle (+/-; add 15' and 5'): + 20' Thrust angle = total toe + 2: + 10' Thrust angle (deviation from direction of travel) = 10' The result is the deviation of the actual running direction from the longitudinal axis of the vehicle.
