Impreza L Sedan F4-2.2L SOHC (1997)
3. When left and right adjusting bolts are turned incrementally by one graduation in the same direction, the thrust angle of the AWD model will
change approximately 10' ["L" is almost equal to 7.5 mm (0.295 inch)] and the thrust angle of the FWD model will change approximately 12' ["L"
is almost equal to 9 mm (0.35 inch)]. Thrust angle: 0° ± 20'. Thrust angle: r = a - b divided by 2.
a = Right rear wheel toe angle.
b = Left rear wheel toe angle.
NOTE: Thrust angle refers to a mean value of left and right rear wheel toe angles in relation to vehicle body center line. Vehicle is driven
straight in the thrust angle direction while swinging in the oblique direction depending on the degree of the mean thrust angle. Here, use only
positive toe-in values from each wheel to substitute for a and b in the equation.
Wheel Arch Height
1. Adjust tire pressure to specifications.
2. Set vehicle under "curb weight" conditions. (Empty luggage compartment, install spare tire, jack, service tools, and top up fuel tank.)
3. Set steering wheel in a wheel-forward position.
4. Suspend thread from wheel arch (point "A" in figure) to determine a point directly above center of spindle.
5. Measure distance between measuring point "A" and center of spindle.
