Driveline System

The front wheel drive (FWD) system is driven by the engine through the transaxle, from the differential to the halfshafts, which drive the front wheels.

The front drive halfshafts have constant velocity joints at both ends. Tripod joints (with tripod, running rollers and tripod housing) are fitted on the transmission side. The joints nearest the wheel are ball joints (with ball star, ball cage and ball shell). The LH tripod joint is secured in the differential with a snap ring. The intermediate shaft (RH side) is secured in the differential by the intermediate shaft bearing. The tripod housing of the tripod joint for the RH front drive halfshaft and the intermediate shaft are attached as a unique part. The wheel-side constant velocity joints are attached to the wheel hubs. The halfshafts are not serviced. If the halfshafts are worn or damaged, install new components.

The FWD driveline system consists of the following components:

• Transaxle assembly
• Front halfshaft - RH
• Front halfshaft - LH

The all wheel drive (AWD) system is driven by the engine through the transaxle to the power transfer unit (PTU). The PTU transfers engine power from the transaxle through the driveshaft to the active on-demand coupling (viscous clutch-type unit). The differential electronic module (DEM) on the active on-demand coupling regulates how much torque is applied to the rear axle and halfshafts. The DEM monitors front wheel speed versus rear wheel speed to determine how much torque (up to 1,000 Nm at the coupler) to apply to the rear wheels. The DEM uses oil pressure via an oil pump and solenoid valve to regulate torque through the active on-demand coupling. The constantly activated, automatic AWD system has no external controls. For information on the PTU, refer to TRANSFER CASE - POWER TRANSFER UNIT (PTU) .

For information on the rear axle, refer to REAR DRIVE AXLE/DIFFERENTIAL .

For information on the front halfshaft, refer to FRONT DRIVE HALFSHAFTS .

For information on the rear halfshaft, refer to REAR DRIVE HALFSHAFTS .

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. For information, refer to ENGINE .

The AWD axle assembly uses 2 types of lubricant. In the rear of the axle assembly, it uses Motorcraft 80W-90 Premium Rear Axle Lubricant XY-80W90-QL meeting Ford specification WSP-M2C197-A. In the front of the axle assembly, it uses Volvo Transmission Oil 116-1641.

The AWD driveline system consists of the following components:

• Transaxle assembly
• PTU
• Driveshaft assembly
• Differential electronic module (DEM)
• Active on-demand coupling
• Axle assembly
• Rear halfshaft - RH
• Rear halfshaft - LH
