Final answer:
Technician A and Technician B are both correct. Power steering leaks can develop in the fitting hoses and seals. The steering components should be observed for leaks while the steering wheel is turned from side to side.
Step-by-step explanation:
Both Technician A and Technician B are correct. Power steering leaks can develop in the fitting hoses and seals, which supports Technician A's statement. Technician B is also correct in observing the steering components for leaks while a helper turns the steering wheel from side to side. This movement helps to put pressure on the system, allowing any leaks to become more apparent.
