SRT-4 L4-2.4L Turbo VIN S (2004)
Axle Shaft: Description and Operation
HALF SHAFT
DESCRIPTION
All Models Except 2.41L Turbo
Vehicles equipped with either an automatic or manual transmission use an unequal-length halfshaft system. The system incorporates two halfshaft
assemblies (left and right) that consist of an inner and outer constant velocity (CV) joint and a solid interconnecting shaft (Fig. 1). The right halfshaft
is longer than the left due to transaxle packaging and powertrain design.
Halfshafts used on both the right and left sides of the vehicle use a tuned rubber damper weight mounted to the interconnecting shaft (Fig. 1). The
damper weight applications vary by which side of the vehicle the halfshaft is located on and the transmission application of the vehicle. When
replacing a halfshaft, be sure the replacement halfshaft has the same damper weight as the original.
Both halfshaft assemblies use the same type of inner and outer joints. The inner joint of both halfshaft assemblies is a tripod joint, and the outer joint
of both halfshaft assemblies is a Rzeppa joint. Both tripod joints and Rzeppa joints are true constant velocity (C/V) joint assemblies. The inner tripod
joint allows for the changes in halfshaft length through the jounce and rebound travel of the front suspension.
