In front-wheel-drive CV joints, which statement is correct?

• A. Most front-wheel-drive vehicles use a fixed CV Joint on at least one axle.
• B. Most front-wheel-drive vehicles use a plunging outboard CV Joint
• C. Both A and B
• D. Neither

Answer: (A)

Front-wheel-drive axles use two CV joints per axle to keep power transfer smooth while the suspension and steering move. A fixed CV joint is one that does not slide in or out along the shaft, preserving a constant shaft length, while a plunging joint can telescope to accommodate changes in distance between the transaxle and the wheel. In most FWD designs, at least one of the two joints on an axle is fixed. This provides a stable connection to the transaxle, while the other joint (often the outer one) may be designed to slide and accommodate suspension travel. Because having at least one fixed joint per axle is the common arrangement, the statement that most front-wheel-drive vehicles use a fixed CV Joint on at least one axle is the best description. The outer joint being plunging is not universal, as some designs also use fixed joints on the outer side.
