Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driveline System: Notes
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 rear driveshaft is connected to the output shaft of the transmission and to the rear axle pinion flange. Universal joints are used at both ends of the driveshaft to allow for angular motions. Slip yokes are used to allow for any changes to the length of 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 rear axle shafts. The shafts rotate the drive wheels.
For information on the driveshaft, refer to DRIVESHAFT .
For information on the rear axle, refer to REAR DRIVE AXLE/DIFFERENTIAL - FORD 8.8-INCH RING GEAR .
The engine angle is built into the engine mounts. If the engine angle is out of specification, the engine mounts must be inspected for damage.
