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 front–wheel as-
semblies. Each axle assembly consists of an inner and anouter constant–velocity 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 can-
not 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 incor-
porate a female spline that installs over a stub shaft pro-
truding from the transaxle.
