2. Remove greasers from both ends of each lower
link inner fulcrum pin.
3. Fit up tool as illustrated in Fig. 21 making sure
that no slackness exists between centres and
greaser holes.
4. The centres of the large end of the taper holes
are found by means of the adjustable adaptor
which can be made on any small lathe. This
item is shown in Fig. 24. Alternatively the taper
. part of a discarded ball socket can be put into
the taper hole and cut off and filed flush at the
largest end of the taper hole. It Is then a simple
matter to mark the centre of the now flush
fitting taper shaft.
5. Using scribing block measure the height of the
scribed lines immediately behind the centres on
brackets, item 3, from the measuring surface,
item 4, see Fig. 21. These heights should be
equal.
6. Measure the height of the centre made on the
drop arm and idler lever (See Fig. 23).
7. From these dimensions subtract those. taken of
the respective centre heights. If the ball pin
heights are correct the results should be the
dimensions shown in Fig. 23.
8. The steering arm ball pin heights are checked
in a similar manner except that the centre
height is taken from the greaser centre at the
rear of the lower link outer fulcrum pin. Owing
to the nearly level underside face of the steering
arm outer end, it is possible to check the steer­
ing arm dimension without plugging its taper
hole.
TO REMOVE AND REFIT UNIT
(See Fig. 14)
Raise the car by placing a jack with a block of wood
or other suitable packing under the front cross­
member.

Place stands under the sidemembers of the under.
frame.
Remove the road wheels.
Disconnect the main hydraulic fluid pipe at the
right-hand side front connector. Wherever it is
necessary to disconnect the brake hoses, do not
allow hydraulic brake fluid to come in contact with
the bodywork, otherwise damage to paint will
result
Place wooden blocks under the sump to support
the engine.
Disconnect front engine mountings from cross­
member.
Remove the two outer track rods from the steering
arms by discarding the split pins, removing the
castellated nuts and using a suitable extractor.
DO NOT DISTORT THE STEERING ARMS INANY
WAY.
Detach the two fulcrum pin brackets from the
underframe by withdrawing two bolts each and
indentlfylng any shims. On later Series IV Cars
onwards, this operation is unecessary as the fulcrum
pin brackets are not used.
Withdraw the four crossmember bolts and washers,
access to these bolts Is gained through the holes
in the underside of the crossmember, remove the
front suspension from under the car by lowering
the jack.
Reverse this procedure for refitting, ensuring that
all location points are clean and free from rough
edges and burrs.
After reconnecting the hydraulic brake
hoses it is essential to bleed the brake system
in order to remove air.
