Inner Joint
WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The inner joints are of the tripot design without an over extension limitation retainer. The left wheel drive shaft uses a female spline which installs over a stub shaft protruding from the transaxle. The right wheel drive shaft incorporates a male spline and interlocks with the transaxle gears using barrel type snap rings.
