Driveline System
The driveline system consists of the following components:
- Center support bearing
- Driveshaft assembly
- Front halfshafts
- Rear halfshafts
- Active torque coupling/rear axle
On Front Wheel Drive (FWD) vehicles, the transaxle transmits power from the engine to the halfshafts.
On All-Wheel Drive (AWD) vehicles, power is transmitted from the engine through the transaxle to the Power Transfer Unit (PTU). The PTU (Power Transfer Unit) transfers engine power from the transaxle to the front halfshafts, and through the driveshaft to the active torque coupling/rear axle and halfshafts. For information on the PTU (Power Transfer Unit), refer to Transfer Case.
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. Refer to Engine.
Vehicle Certification (VC) Label Example
The Vehicle Certification (VC) label is located in the driver door jamb. The axle code is on the VC (Vehicle Certification) label.
The axle ratio's used are 3.16, 3.21, 3.36, and 3.39. The ring gear has a diameter of 174 mm (6.85 in).
The wheel speed sensor rings for FWD (Front Wheel Drive) vehicles are located on the front halfshafts and are mounted to the rear inner spindles.
The wheel speed sensor rings are located on the front and rear halfshafts for AWD (All-Wheel Drive) vehicles.
