Original BMW Left CV Axle Assembly (D=35 mm) for BMW 2 Series, 3 Series, and 4 Series (2012–2021)

Weighing 8.9 kg (19.5 lb), this Original BMW left CV axle assembly carries drive to the left wheel of 2012–2021 BMW 2 Series, 3 Series, and 4 Series models, from the 335i and 435i to the 340i, 440i, and M240i. BMW calls it the output shaft, left, and marks this version D=35 mm in its parts data, with production starting in November 2011. Like every CV axle, it combines a shaft with a constant velocity joint at each end, one joint connecting toward the transmission and one at the wheel hub. Together they let the axle change angle and length as the suspension travels, so power stays steady over bumps. BMW supplies it as one complete piece.

Original BMW Parts carry a 24-month parts warranty.

The D=35 mm marking identifies this version of BMW's left output shaft. The shaft spans two engine generations, the N55 in the 335i, 435i, and M235i and the B58 in the 340i, 440i, 440i Gran Coupe, and M240i. It also covers the N20-powered 228i xDrive. It serves both standard and xDrive cars, though xDrive coverage here is limited to the 228i xDrive, 335i xDrive, and 435i xDrive.
