The open differential comprises a pinion shaft with a hypoid gear, and a crown wheel drive gear attached to a differential case. The differential case houses two planet gears and two sun gears.
An input flange is installed on the externally splined outer end of the pinion shaft and retained by:
- a circlip on vehicle's fitted with the 4-cylinder engine,
- a nut on vehicle's fitted with the V6 engine.
The input flange has six threaded holes for the driveshaft attachment bolts. An oil slinger and oil seal are installed in the carrier to seal the input flange. The hypoid gear of the pinion shaft mates with the drive gear.
The drive gear is welded to the differential case. The differential case is mounted on taper roller bearings located in machined bores in the carrier and the cover. Shims are installed behind the bearing cups to apply the correct bearing preload and hypoid backlash.
The differential case has a through hole, which provides location for a shaft. Two planet gears are installed on the shaft, with thrust washers between the planet gears and the differential case. A roll pin locks the shaft to the differential case.
Two sun gears are located in pockets in the differential case and mesh with the planet gears. Spacers are fitted between the sun gears and the differential case to give the correct mesh contact between the planet gears and the sun gears. Each sun gear has a machined bore with internal splines and a machined groove. The splines transfer drive to the halfshafts. The groove provides positive location for the snap ring fitted to the inboard end of the halfshafts.
Oil seals are installed in the carrier and the cover to seal the halfshafts.
The open differential contains a quantity of oil for splash lubrication of the internal components. A magnetic drain plug is installed in the bottom of the carrier and a filler/level plug is installed in the cover.
