Front driveshaft for 2012-2017 Ram 1500 4WD trucks with the 6-speed automatic. Replaces Mopar 52123021AD, 52123021AE and Dorman 938-090.
This is the front driveshaft for the 2012-2017 Ram 1500 4WD with the 6-speed automatic. It replaces Mopar 52123021AD and 52123021AE and crosses to Dorman 938-090 and 65-3019.
Ram used more than one front shaft in these years. Trucks with the 8-speed automatic take a different shaft (938-095, 52123639AA), and 2002-2006 trucks take 938-150. Check the transmission and the part number on your old shaft before you order.
A worn front shaft on these trucks causes a clunk when you shift into 4-high, a vibration that shows up only in 4WD, or a knock through the floor on takeoff. The shaft is 33.07 in. long end to end with a 30-spline end. Mark the flange positions before removal and compare the length on the bench before install.
