Question

technician a says that on most modern vehicles, the joints are sealed and lubricated for life, so there may be no grease fittings present. technician b says that you should add grease to the ball joint until all the old grease is pushed out past the rubber boot on the joint. wh is correct? a. technician a b. technician b c. both technician a and technician b d. neither technician a nor technician b

Explanation:

• Technician A: Modern vehicles often have sealed - for - life joints with no grease fittings. This is a common design feature in contemporary automotive engineering to reduce maintenance needs.
• Technician B: Adding grease until old grease is pushed out past the rubber boot can damage the boot (if over - greased) as it is not designed to have excessive pressure from over - filling. The correct practice is to follow the manufacturer's guidelines for greasing (if applicable), which usually do not involve over - greasing until old grease is forcefully expelled in that manner.

Answer:

a. Technician A
