the track is double the amount shown on the dial).
Re-tighten the track rod end lock-nuts.
When tightened, it is important that the sockets
at either end of each track rod are centrally
disposed with the ball pins so that the track rod
may be free to turn slightly.
If the wheels are badly out of alignment, this may
be due to a track rod (cross tube) having bent
through accidental damage. In such cases the track
rod should be renewed.

With optical gauges or any type that does not
require the road wheels to be turned through 180 °
it is vital that the wheel run-out should be checked
and the points of maximum run-out set In the
vertical position.
Setting of outer track rods
If new track rods are being fitted after accident
damage, or if excessive tyre wear is present, the
following procedure should be observed to ensure
correct Ackerman (toe-out on turns) when the
wheel track is correct.
1. Disconnect each outer track rod inner ball
joint from the drop arm and idler lever .
2. Count the number of steering wheel turns
from lock to lock (in the steering unit).
3. Obtain the mid position of the steering unit by
turning the wheel back half this amount from
full lock,
and keep it
in
this position.
N.B. It is most important that great accuracy
is observed when carrying out Items 2 and 3,
and it is recommended that the steering unit
is marked appropriately and a datum line or
pointer is used to achieve this.
4. If necessary, reposition the steering wheel on
its splines so that the spokes are straight across.
5. Reconnect track rods to drop arm and idler
lever.
6. Prepare the car for a steering geometry check
as described in this section under TO CHECK
AND ADJUST FRONT SUSPENSION
DIMENSIONS AND SETTINGS.
7. Check the measurement at the front of the
car between the centre of each tyre tread
and the greaser on the lower link inner fulcrum
pin.
8. These measurements should be equal on each
side with the steering unit and idler lever in
the straight ahead position.
9. Adjust each outer track rod until these
measurements are equal.
