Clunking, vibration, or failure to engage four-wheel drive on certain Ram 1500 trucks can indicate damage within the front differential assembly. Even when the shift actuator is functioning properly, stripped intermediate shaft splines and bearing failure can prevent the 4WD system from engaging.
This TrakMotive technical bulletin highlights a common failure affecting 2012-up Ram 1500 4WD applications and introduces the CH-3511RK Intermediate Shaft Repair Kit. The kit includes a replacement intermediate shaft, needle bearing, and necessary components to address the problem without replacing the entire differential.
The bulletin also explains why technicians should inspect the connecting CV axle for damage and outlines recommended replacement options, including OE Replacement, HD Xtreme™, and Xtended Travel™ CV Axles.
