Driveline System: Notes

WARNING: This page is about a different car, the 2012 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

The driveline system consists of the following components:

Rear drive axles with varying diameter ring gears and differential designs
One-piece rear driveshaft with 2 U-joints and a front slip yoke or flange
Two-piece rear driveshaft with a CV joint and a center support bearing
Limited slip axle - Ford 8.8-in rear axle

The source of the drivetrain's power is generated by the engine and delivered to the transmission. The driveline transfers the engine torque through the driveshaft to the axle. The driveshaft is connected to the output shaft of the transmission and to the axle. Vehicles with 3.7L engines use U-joints at both ends of the driveshaft to allow for angular motion. A slip-in-tube driveshaft is used to allow for any changes to the length of the driveshaft. Vehicles with 5.0L or 5.4L engines use a CV joint in the rear of the driveshaft and a U-joint in the front. A center bearing and the CV joint allow for length changes to the driveshaft. The engine torque enters the axle through the drive pinion, which rotates the ring gear. The ring gear is mounted to the differential case, which contains the gears that transmit power to the axle shafts. These shafts rotate the drive wheels.
