Question

Technician A is correct because Steering Axis Inclination (SAI) is indeed designed to make the spindle travel in an arc during turning, which helps in vehicle stability and steering returnability. Technician B is incorrect because FWD vehicles typically have a greater SAI angle than RWD vehicles, not the other way around. This is due to the design differences in the suspension systems of FWD and RWD vehicles.
