AXLE TUBE
Replacing the Centre Bearing Bushes :
The rubber bushings in the centre bearing can be replaced either with axle
tube removed from the car or while it is still in position.
To replace the bushing with the axle tube in position, detach the rear
silencer and exhaust pipe from the brackets at the wheel arch and the floor
pan. Unscrew the retaining nut and remove the bolt through the centre
bearing. Pull the axle tube down and insert a bar on each side of the centre
bearing between the axle tube and the under body to hold it down.
Remove the rubber bushing, using Tool No. 784033 (Fig. I: 13). Use the
same tool to install the new bushing. Remove the two support bars, raise
the axle tube and fit the bolt through the centre bearing. DO NOT tighten
the nut at this stage. Refit the exhaust pipe and silencer to their brackets.
Lower the car. Tighten the nut on the centre bearing bolt.
Removal:
Remove the squab and back rest from the rear seat. Jack up the rear of the
car, fit safety stands and remove the road wheels. Detach the rear silencer
and exhaust pipe from the brackets at the wheel arch and floor pan.
Disconnect the shock absorber or link at the axle tube. Unclamp the hand-
brake cables from the axle tube. Detach the cable ends from the levers on
the brake backplates. Disconnect the brake hoses at the body. Unfasten the
stop strap at its rear bracket and allow the axle to drop down. Lift out the
suspension coil springs. Unscrew the four retaining bolts securing the centre
bearing to the floor pan (Fig. I: 12). From inside the car, unscrew the two
nuts securing each of the locating link body brackets to the floor pan
(Fig. I: 14). The entire axle assembly can now be removed from the car.
Installation :
Installation is the reverse of the removal procedure with special attention
to the following points :-

If new rubber bushings· have been fitted to the axle assembly, the
bearings concerned must not be tightened until the weight of the car
is standing on its wheels.
The coil springs must be installed with the unground end facing down-
wards. Turn the spring until it is correctly located in the lower seat.
The end of the stO}l strap must project 0.6 in (15 mm) beyond the
attaching bracket (Fig. I: 11).
Bleed the brakes as described in the BRAKES section.
LOCATING LINKS
Replacing the Bushings :
Unscrew the retaining nut and remove the bolt securing the locating Hnk
to the axle tube. Similarly detach the link from its body bracket. Removal
of the bushings will be facilitated if the eye around the bushing is first
heated with a flame. Press out the bushing with driver, Tool No. 784076.
Install the new bushing using the same tool (Fig. 1:15).
Position the link in the body bracket and fit the bolt through the bushing.
When the bolt and retaining nut is tightened the angle between the link and
the bracket mounting face should be 4 ± 2° (Fig. I: 16). Connect the link
to the axle tube and insert the bolt into the bushing from the outside.
DO NOT tighten the retaining nut until the weight of the car is on its wheels.
