Original BMW Front Left CV Axle Assembly for BMW X3 and X4 (2018–2024)

This Original BMW front left CV axle assembly sends drive to the left front wheel of the 2018–2024 BMW X3 and the 2019–2024 BMW X4, including the X3 M and X4 M. BMW names it the output shaft, front left, and its parts data shows production beginning in August 2017. The assembly pairs a shaft with a constant velocity joint at each end. The inner joint connects toward the transmission and the outer joint connects to the wheel hub. Those joints let the shaft change angle and length as the suspension moves and the front wheels steer, so torque keeps reaching the wheel through turns and over bumps. BMW supplies it as one complete piece.

Original BMW Parts carry a 24-month parts warranty.

BMW has since superseded 31-60-8-643-183 with part number 31-60-8-680-337, and both numbers identify this same front left shaft. On BMW's axle diagram for the X3 and X4, it appears as position 1. A single left shaft covers the G01 and G02 xDrive models as well as the F97 and F98 M models. An X3 xDrive30e, an X4 M40i, and an X3 M Competition all take this same part on the left side, despite their very different engines.

Common Questions

Is 31-60-8-643-183 still the current BMW number?
BMW has replaced it with 31-60-8-680-337 for the same front left position. Either number identifies this shaft.

What are the signs of a failing front CV axle on an X3 or X4?
A clicking or popping noise when turning, especially in sharp turns, usually means a damaged or worn CV joint. Vibration while driving at higher speeds can point to a bent shaft or worn joints.

Why is there grease on the inside of my front wheel?
Grease there usually means the CV boot has torn or cracked and is losing lubricant. A joint running short of grease wears faster.
