47-2 DESCRIPTION AND OPERATION
Description
General
Front and rear propeller shafts transmit the drive from the transfer box to the axles.
On vehicles from 03 model year fitted with the 4.6l V8 engine and 4HP24 transmission, the front propeller shaft is 15
mm (0.6 in) longer and the rear propeller shaft is 15mm (0.6 in) shorter than those used on vehicles with the 4.0l V8
and Td5 engines. This is to accomodate an increase in length of the 4HP24 transmission.

DESCRIPTION AND OPERATION 47-3
Front propeller shaft
1Hookes joint
2Grease nipple
3Universal joint4Gaiter/Sliding spline joint
5Lubrication point
The front propeller shaft consists of a tube with a universal joint and a sliding spline joint at the front end, and a
Hookes joint at the rear end. The universal joint is bolted to the pinion flange of the front axle differential. The Hookes
joint is bolted to the front output shaft of the transfer box.
The Hookes joint is lubricated during manufacture and sealed for life. A grease nipple is installed in the universal joint
to lubricate the serviceable, sealed needle bearings of the joint. The sliding spline joint is sealed with a gaiter and
lubricated through a lubrication point on the tube. Because of the proximity of a chassis crossmember to the front
propeller shaft, the lubrication point is normally sealed with a grub screw. During maintenance, the grub screw is
temporarily replaced by a slave grease nipple to lubricate the sliding spline joint.

2Grease nipple
3Universal joint4Gaiter/Sliding spline joint
5Grease nipple
The rear propeller shaft consists of a tube with a universal joint and a sliding spline joint at the front end, and a flexible
coupling bolted to the rear end. The universal joint is bolted to the rear output shaft of the transfer box. The flexible
coupling is bolted to the pinion flange of the rear axle differential.
A grease nipple is installed in the universal joint for lubrication of the serviceable, sealed needle bearings in the joint.
The sliding spline joint is sealed with a gaiter and lubricated through a grease nipple in the tube.

The following bearing replacement procedure
applies to the universal joints of both the front and
rear propeller shafts, including the Hookes joint (i.e.
double universal joint) of the front propeller shaft.
Disassembly
1.Remove propeller shaft:
lFor front propeller shaft.

+ PROPELLER SHAFTS, REPAIRS,
Propeller shaft - front.
lFor rear propeller shaft.

+ PROPELLER SHAFTS, REPAIRS,
Propeller shaft - rear.
2.Thoroughly examine the universal joint for
signs of damage or wear.
3.Clean the universal joint bearing cups and
circlips.
CAUTION: Before removal, mark the
position of the spider pin relative to the
journal yoke ears on the propeller shaft
joint. This will ensure correct assembly and
reduce the possibility of imbalance.
4.Remove the circlips.
5.Tap the yokes to eject bearing cups. Remove
bearing cups.
6.Remove spider from yokes.
7.Clean yokes and bearing cup locations. Reassembly
1.Remove bearing cups from new spider.
2.Check all needle rollers are present and
correctly positioned in bearing cups.
3.Enter new spider, with seals, into one of the
yokes.
4.Partially insert one bearing cup into yoke and
enter spider trunnion into bearing cup.
5.Insert opposite bearing cup in yoke.
6.Press both cups into place.
7.Press each cup into its respective location in
yoke up to lower land of circlip groove. Damage
may be caused to cups and seals if cups
pass this point.
8.Fit circlips and check no end float exists.
9.Engage spider in second yoke. Fit bearing cups
and circlips as described in steps 4 to 8.
