Which components are evaluated for wear during Driveshaft Inspection?

Which components are evaluated for wear during Driveshaft Inspection?

• A. Both driveshafts and universal joints
• B. Only driveshafts
• C. Only universal joints
• D. Neither

Answer: (C)

The key idea is that wear in a driveshaft is found where the moving parts operate—the universal joints. U-joints have bearings, cups, and seals that are lubricated and subject to wear from rotational movement and torque changes. Over time this wear shows up as looseness, binding, play, or leaks, and that’s what you evaluate during a Driveshaft Inspection. The driveshaft tube itself is a rigid structural member; it can be checked for damage like dents or cracks or for misalignment, but it isn’t a wear item in the same way the joints are. So the best answer is that only the universal joints are evaluated for wear.
