Section 10 (HALFSHAFT): Description

WARNING: This page is about a different car, the 2022 RAM ProMaster 3500, 2022 RAM ProMaster 2500, and 2022 RAM ProMaster 1500. However, it is still accessible from the selected car via links, so may be relevant.

This vehicle is equipped with an equal length halfshaft system, consisting of short halfshafts on both sides with an intermediate driveshaft on the right side. The halfshafts consist of a fixed Constant Velocity (CV) joint at the outboard end connected by a solid shaft to a plunging CV joint on the inboard end. The inner CV joint has a splined connection into the transmission, or onto the intermediate driveshaft, and is retained with a snap ring. The outer joint has a spline connection to the wheel hub and is retained with a steel lock nut.

All the halfshaft assemblies use the same type of inner and outer joints. The inner joint is a tripod joint that allows for the changes in halfshaft length through the jounce and rebound travel of the front suspension. The outer joint is a Rzeppa joint that allows articulation during front suspension travel and steering. Both tripod joints and Rzeppa joints are true constant velocity CV joint assemblies.
