Inner Joint
WARNING: This page is about a different car, the 2008 Pontiac G5 and 2008 Chevrolet Cobalt. 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 inner joints incorporate a male spline which interlocks with the transaxle, or the intermediate drive shaft if equipped, using snap rings.
