GENERAL DESCRIPTION AND SYSTEM OPERATION
FRONT DRIVE AXLE
General Description
Drive axles are flexible shaft assemblies that transmit rotational force from the transaxle to the frontwheel assemblies. Each axle assembly consists of an inner and an

outer constantvelocity joint connected to an axle shaft. The inner joint is completely flexible and has the ability to move in and out. The outer joint is also flexible, but it cannot move in and out. The drive axles use one type of outboard joint and one type of inboard joint. The inboard ends of both drive axles incorporate a female spline that installs over a stub shaft protruding from the transaxle.
