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

constantvelocity joint 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 two types of inboard joints.
