a Refer to the appropriate procedures.
The all wheel drive (AWD) system consists of the following
- Power transfer unit (PTU)
- Rear driveshaft
- Four wheel drive (4WD) control module
- Rear axle with coupling device
The PTU is a gearbox that attaches to the transaxle. The RH intermediate shaft passes through the PTU and engages the differential side gear as in normal front wheel drive (FWD) applications. The PTU directs power to the rear driveshaft through a helical gear spline coupled to the transaxle differential case, a helical gear drop (idler gear) and hypoid/helical ring gear assembly and pinion set. The PTU is sealed from the transaxle and has its own oil sump.
Serviceable components of the PTU are limited to the output shaft seal and flange, intermediate shaft seal and deflector, and the PTU-transaxle compression seal. The internal components are not serviced. Do not remove the cover of the PTU. If any of the geared components, bearings, case cover or internal shafts are worn or damaged, a new PTU must be installed.
Refer to FOUR WHEEL DRIVE (4WD) SYSTEMS.
