STEERING GEOMETRY
1) What is the wheelbase of the truck?
Use the string, framing square, and triangle provided to answer the next questions.
2) What is the angle from the center of the kingpin, through the center of the tie rod end, to the centerline of
the truck?
Right
Left
3) What is the steering angle of the right wheel with the wheels turned all the way to the right?
4) What is the steering angle of the left wheel with the wheels turned all the way to the right?
5) What will happen if toe-in is measured in a left turn wheel position? What is the actual measurement?
6) Are we concerned with Ackerman geometry on a truck more than on a car?
7) What will happen if the frame and wheelbase is lengthened in regards to steering geometry?
8) Why does the Caster/Camber gauge have a side to side level?
9) Where should the steer tires be pointing to check camber? Why?
