What is true regarding "Tripod" CV joints?

"Tripod" CV joints are designed to accommodate the in-and-out movement of the halfshaft, which is essential for maintaining proper function in vehicles that have independently suspended front or rear axles. This ability to plunge is critical because as the suspension moves—whether it is compressed or extended during driving, cornering, or going over bumps—the halfshaft needs to adjust its length to keep a reliable connection between the transmission and the wheels.

This design allows for flexibility as it absorbs suspension travel without binding or affecting the angle of the joint. Typically, tripod joints are used in applications where the axle needs to move freely with the suspension components while providing the necessary torque to drive the wheels. The presence of this plunging ability is what distinguishes them from other types of CV joints like ball-type joints, which may not provide the same range of motion.

Other options provide inaccurate information regarding the capabilities and applications of tripod CV joints. For example, they are commonly used in various vehicles, not just trucks, and they do not contain four roller bearings; instead, they typically use three. Additionally, they are specifically designed to handle some suspension movement, which is contrary to one of the other statements. Thus, the assertion that they allow the halfshaft to plunge in and
