Operation 1 Drive shaft removal
1.
Place the vehicle on a ramp, or on axle stands under the
chassis.
2. Unscrew four bolts, nuts and locking washers from the
coupling flange at the axle end, to allow the shaft to be lowered to
facilitate access to the front flange. Now remove the four bolts, nuts
and lock washers at the gearbox flange and remove the drive shaft.
Operation 2 Checking the drive shaft for wear.
The degree of wear on the drive shaft thrust faces can be determined
by the amount of lift in the joints. This can be measured by hand using
a piece of wood suitably pivoted. Any circumferential movement of
the shaft relative to the coupling flange yokes indicates wear in the
needle roller bearings or the drive shaft spline, or ovality in the yokes.
A unit package (joint repair kit) is available for replacing worn needle
bearings and journals but if excessive wear is apparent in the yoke
bearing or drive shaft splines no action is possible and the drive shaft
will need to be renewed as a complete assembly.
Operation 3 Drive shaft - dismantling and re-assembly
To dismantle
1. Using circlip pliers (general tool No. 7066) remove the four
circlips from the universal joint.
Note: If no circlips are fitted, as may be the case on late vehicles, then
the yoke bearings are "staked" in to position. These shafts are sealed
and cannot be overhauled and a new drive shaft assembly complete
will need to be procured and fitted.
It may be necessary to clean rust and paint from the yokes to enable
the circlips to be removed.
2. Tap the radius of the yoke with a hide mallet to release the
yoke bearings. Should this prove difficult then the bearings can be
gently prised out from inside the yoke. Withdraw the bearing cups and
disengage the journal from the yoke.
3. Repeat the sequence 1 and 2 on the remaining bearings,
removing the journal from the yoke on the drive shaft.
4. Similarly separate the yoke and journals at the opposite end
of the drive shaft.
5. Unscrew the dust cap to separate the two sections of the
drive shaft at the sliding spline.
To re-assemble
1. Re-assemble the two parts of the drive shaft checking
carefully that the arrows stamped on them align correctly. This is to
ensure that the coupling flanges are correctly in line with each other,
thus giving uniform notion of the drive shaft plus the shaft balance
will be maintained. Failure to do this will cause accelerated wear of
universal joints, gearbox output bearings and axle input bearings as
well as a very poor driving experience. Tighten the dust cap.
2. Remove the cups from the new spider journals.
3. Ensure that the cups contain an approved lubricant (one
third full, leaving an air space to allow for heat expansion) and that all
the needle rollers are in position.
4.
Fit the spider to the drive shaft yoke, locating the journals
in the yoke and carefully press both bearing cups in to position,
ensuring that the spider trunnion engages the cups and that the
needle bearings are not displaced. repeat this operation for the other
journal.
5. Using two tools of slightly smaller diameter than the
bearing cups, press the cups in to the yokes until they reach the lower
land of the circlip grooves. Do not press the cups below this point or
damage may be caused to the cups, bearings and seals.
6.
Fit the circlips.
Operation 4 Drive shaft - refitting
To replace
1. Align the drive shaft with the gearbox coupling flange and
secure with four bolts, nuts and lock washers. Tighten to a torque of
3.46 to 5.15 kg/m (25 to 30 lb/ft).
2. Repeat for the rear drive shaft coupling flange to the axle
coupling flange.
