Screw the ball housing locking

the lock washer. On models not fitted with a lock
washer, fit a new locking ring. Refit the seat spring,
seat, tie-rod and ball housing, and tighten up until
the tie-rod is pinched. Slacken the housing one-
eighth of a turn and tighten the locking ring to the
recommended torque. Punch the lock washer into
the slots of the housing and locking ring. If no lock
washer is fitted, punch the lips of the locking ring
into the slots of the ball housing and rack.

Section J.4
FRONT WHEEL ALIGNMENT
Checking
When checking or adjusting the front wheel alignment
it is essential to use equipment designed to work at the
specified height and diameter, and preferably a gauge
which measures the angles involved rather than the
difference in distance between the wheels in front of
and behind the centres.
With the car unladen, tyres at the correct pressures, and
the steering in the straight-ahead position, each wheel
should make an angle of 7' 30" with the longitudinal axis
