The drivetrain is a collection of components in your BMW F80 (2015+) that transfer power from the transmission to the wheels and drive it forward. These components include the driveshaft, CV joints, the differential, axle shafts and the U-joints. A driveshaft is a long tube of steel that is linked to a car’s transmission at one end and the wheels at the other. The axle shafts are a single rotating shaft, on either side of the differential which delivers power from the final drive assembly to the drive wheels.
