Question

Quizplus · Accepted Answer

Technician B is correct because staking the axle hub nuts after they are tightened is a common practice to lock them in place and prevent them from loosening. Using an impact wrench to tighten axle hub nuts, as Technician A does, can lead to over-tightening and damage, so it's not the recommended method.
