Dogtracking Diagram
3.
When a vehicle with these tread differences is driven on a crowned road, front end may tend to ride higher than the rear. This makes the vehicle
appear to dogtrack. Perform inspection to determine if a problem actually exists.
DIAGNOSIS
Dogtracking Measurement
1.
Use an empty stretch of road or parking lot.
2.
While sighting down hood or body style line, drive vehicle to see if it is going straight or dogtracking.
3.
Stop vehicle when you notice dogtracking. Have an assistance mark center tread of both front tires with chalk on the ground.
4.
Slowly pull vehicle forward until rear tires are at same position as marks made for front tires.
5.
Have an assistance mark the ground as was done for front tires. Identify which marks are for each set of tires.
6.
Move vehicle out of way and measure total amount of dogtracking as follows:
^ Measure distance A between front tire marks.
^ Measure distance halfway between these two marks.
^ Measure distance B between rear tire marks.
^ The distance between the two center marks, C, is the amount of dogtracking present in the vehicle.
King Pin Inclination
Kingpin inclination is not adjustable and is set to specifications during production. Whenever kingpin inclination is not within the specified angle, check
all parts of front suspension and body alignment. Repair or replace defective part(s) as required.
