What condition should the drive shaft and U-joints be in during inspection?

The correct choice highlights that the drive shaft and U-joints must be in a condition described as "PMS," which stands for "Properly Maintained and Serviced." This means that during inspection, these components should not show any cracks or broken sections, as such damage can compromise the vehicle's ability to operate safely. Additionally, properly greased U-joints are essential for ensuring smooth operation and minimizing wear and tear, which can lead to failures.

Proper maintenance of the drive shaft and U-joints is critical for the overall performance of the vehicle. If these components are not maintained, it can result in serious mechanical issues, such as vibrations, loss of power transmission, or complete drive shaft failure, which can be dangerous while driving. Therefore, regular inspections that confirm the integrity and maintenance of these parts are vital for safety on the road.

In contrast, options mentioning visible rust and damage, loose connections, or signs of wear indicate potential problems that could lead to safety hazards. Thus, the emphasis on being properly maintained and serviced is paramount for ensuring vehicle reliability and safety.
