The Churchill equipment consists of tracking gauge
and camber/castor and steering axis Inclination
checking gauge.
The Weaver equipment consists of turntable and
wheel alignment indicator.
The Weaver wheel alignment Indicator will be
found to be unsuitable for cars fitted with centre
lock wire wheels due to recessing of the stub-axle
end nut within the hub. The Churchill camber
gauge should therefore be used.
Illustrations of the various tools in use are give,n in
the following pages.

PREPARATION OF VEHICLE
When carrying out checks on the front suspension
and steering dimensions, the following require­
ments must be met. It should be noted that item 5
entirely supersedes previous methods of obtaining
the static laden condition.
1. The car must be placed on a perfectly level
floor or level ramp.
2. Tyres must be inflated to their correct
pressures and have the same amount of wear.
3. For checking the front wheel track the car
should be in a normally laden condition.
4. Both front wheels must be checked for "run­
out". To do this, spin each wheel, holding a
piece of chalk close to the sidewall of the tyre.
By moving the chalk progressively nearer the
tyre until It makes contact, the point of greatest
"run-out" will be marked.
Always set the wheels so that the points of
"run-out" are well away from the points of
contact of any gauges which may be used.
Therefore when checking camber, castor and
steering axis Inclination set the "high-spots"
horizontally opposite one another, and when
checking toe-in set them vertically.
5. The car Is loaded on to four gap gauges by
placing weights at the front of the car. The
amount required Is approximately 300 lb.
(136 kg.) evenly distributed on a platform,
comprising of a wooden plank supported by
two suitably cranked steel bars ¾ In. (22 mm.)
square inserted into the front jacking sockets.
At the front, steel gap gauges are used, see
Fig. 2 or 28. At the rear, hardwood gap· gauges
are used; these are shaped to clear the hydraulic
pressure pipes, the bump rubbers and fit round
the axle casing, see Fig. 3. Normally the rear
· end of the car is I ifted by hand to enable the rear
