What is the most likely cause of a slight vibration in a manual transaxle during turns?

• A. Worn inner axle U-Joint
• B. Loose differential case assembly
• C. Out of balance half shaft
• D. Worn outer axle U-joint

Answer: (D)

A slight vibration in a manual transaxle during turns is most likely caused by a worn outer axle U-joint. The outer U-joint connects the axle shaft to the wheel hub, allowing for the necessary flexibility during turns. When the vehicle turns, the outer U-joint must accommodate the varying angles and changes in position. If the U-joint is worn, it may not function properly, leading to vibrations that can be felt in the vehicle. This can occur especially during maneuvers that require turning, as the added stress on a deficient joint is greater at these angles. The vibration can be exacerbated during tighter turns or when the vehicle is under load, highlighting the correlation between the U-joint's condition and the operational demands placed on it in such scenarios. Maintaining the integrity of the outer axle U-joint is critical for smooth handling and ride quality. When considering the other options, while they could lead to vibrations in other circumstances, they do not specifically relate to the symptoms experienced during turns in the same direct manner.
