Power is transmitted from the transaxle to the wheels through a pair of axle shafts, with the inner ends splined into the differential side gears and the outer ends splined to the axle hubs, secured by a large nut. The inner ends feature tripod-type constant velocity joints that allow for both angular and axial motion, while the outer joints are of the ball and cage type. Periodic inspection of the boots for damage and leaking lubricant is essential, as torn CV joint boots must be replaced promptly to prevent damage to the joints. Common symptoms of worn or damaged CV joints include lubricant leaks, a clicking noise during turns, a clunk when accelerating after coasting, and vibration at highway speeds. To check for wear in the CV joints and axle shafts, grasp each axle individually and rotate it in both directions while holding the CV joint housings, feeling for play that indicates worn splines or loose CV joints.
