Checking Toe-In

1987 Saab 9000 L4-1985cc 2.0L DOHCSECTION Checking Toe-In





USING A TRACKING GAUGE
1. Roll the car forwards on a perfectly level surface and allow it to come to a stop without using the brakes.
2. Using the tracking gauge measure dimension A between the wheel rims at axle height.
a. Mark the measuring points with chalk.
b. Roll the car forwards until the chalk mark comes to the axle height.
c. Measure dimension B.

^ In this method, the tracking gauge remains in the same position on the floor for both measurement A and B. This ensures that any unevenness in the surface of the floor will not influence the measurements.

3. If adjustment is necessary, do this by adjusting the length between the track rod and the inner ball joints on both sides of the car. Slacken the locknut at the track rod end and the outer clip securing the gaiter on the steering rack.
4. Gripping the track rod with a suitable wrench, turn it either clockwise or counterclockwise a number of turns according to the table until the correct toe-in is achieved. Make sure that the gaiter does not turn back with the track rod. Install the clip and tighten the locknut.

IMPORTANT: Check the track rod length.

5. Treat the track rod threads with an anti-rusting agent after tightening.





MEASURED BETWEEN RIMS
Use the table according to the following example.
1. Assume that the tracking gauge gives a reading of 0.5 toe-out.
2. Find this value in the toe-out section of the first column and follow the line across to the second column, that gives the number of required turns: "0.5 out". This means that together the two track rods must be rotated 0.5 turns, that is to say each track rod should be rotated 0.5 turns outwards or counterclockwise.
