Power is transmitted from the transaxle to the rear wheels through a pair of Axle Shaft. The inboard end of each Axle Shaft is connected to the transaxle by a side gear shaft, which can be easily replaced if necessary. The outboard ends of the Axle Shaft are splined to the axle hubs and locked in place. The splined inboard ends of the Axle Shaft have sliding tripod joints that allow for both angular and axial motion. These joints are rebuildable. The outer joints, which consist of ball bearings, only allow for angular movement and are not rebuildable. Regular inspection of the CV Boot is important to check for damage or leaks. Damaged CV joint boots should be replaced promptly to prevent damage to the joints. Signs of worn or damaged CV joints include lubricant leaks, clicking noise in turns, clunking when accelerating, or vibration at highway speeds.
