Question

steering and suspension - final exam
this exam consists of 25 questions. answer each question.
two technicians are discussing alignment angles on a fwd vehicle.
technician a says that toe-in should be used on all front axles.
technician b says that toe-out should be used because it is a drive axle.
who is correct?
both technicians a and b.
technician a only.
neither technician a or b.
technician b only.

Explanation:

For a front - wheel - drive (FWD) vehicle, the front axle is a drive axle. When the vehicle is moving, the driving force on the front wheels causes them to tend to toe - out. So Technician A is wrong as toe - in is not suitable for all front axles (especially FWD front axles which are drive axles). Technician B is correct because for a FWD vehicle, the front axle being a drive axle means toe - out is appropriate to counteract the toe - in tendency caused by the driving forces.

Answer:

Technician B only.
