1 Description and
maintenance

1 The steering gear is of rack and pinion type
with a universally-jointed column which
incorporates a steering lock and ignition
switch.
2 The steering wheel is of two spoke type on
all models except the SX which has four
spokes.
3 The system is maintenance-free except to
check occasionally the pinch-bolts.
4 At the intervals specified in “Routine
Maintenance” carefully inspect the rack gaiters
for splits, particularly at the bottom of the
vees, as a split here can often go unnoticed.
5 Check the tie-rod balljoints for wear. To do
this, have an assistant turn the steering wheel
repeatedly in both directions through an arc of
about 10 or 15 degrees. Observe the balljoints
for lost motion or slackness. If evident, renew
the balljoint as described in Section 2
