Quizplus · Accepted Answer

Technician A is correct because placing a finger over the breather hole helps to ensure grease is forced through the splines rather than escaping through the hole, ensuring proper lubrication. Technician B is correct because relieving the weight on the 5th wheel allows for better access and ensures the grease can be more effectively applied to the pivot pins, ensuring proper lubrication and reducing wear.
