Technician A says that the springs support the vehicle's weight. Technician B says that a shock absorber controls both jounce and rebound in the suspension. Which technician is correct?

Both Technician A and Technician B are correct. The springs in a vehicle's suspension system are designed to support the weight of the vehicle and absorb any impact from the road. On the other hand, the shock absorbers control the movement of the springs, dampening the jounce (upward movement) and rebound (downward movement) in the suspension. This helps to keep the vehicle stable and the ride smooth.
