Front prop shaft for Mercedes 4MATIC E400, E550, C400, CLS550, S550 and CL550 with the 7-speed automatic. Replaces A2044107001 and Dorman 938-255.
This front driveshaft fits Mercedes-Benz 4MATIC models that use part number A2044107001: E400 2015-2016, E550 2012-2016, C400 2015, C450 AMG 2016, CLS400 2015-2016, CLS550 2012-2016 (7-speed automatic), S550 2012-2017 (7-speed automatic on 2014-2017 cars) and CL550 2011-2014. It crosses to Dorman 938-255. It is a different part from the W204/W212 shaft 938-241, so match the part number on your old shaft.
On 4MATIC cars the front shaft runs from the transfer case beside the transmission to the front differential. When its joints wear you get a clunk on takeoff, a vibration under light throttle, or a knock when you move from reverse to drive.
Overall length is 26.42 in., measured end to end, with a 22-spline end. Check both against the old shaft on the bench before you install it.
