3. Front Wheel Alignment
a. Sequence of Operation
Correct wheel alignment is necessary to keep
the front wheels in their true running position,
and to prevent tire wear and hard steering. Tire
wear is affected, as far as front end alignment
is concerned, by incorrect toe-in or excessive
camber. Incorrect caster has little effect on tire
wear.
Always check front wheel alignment whenever
any front suspension part is removed and in-
stalled, or in cases of tire wear, or of driver
complaint on handling.
The following operations should be performed
in the order listed whenever front wheel align-
ment is checked and adjusted.
1. Check tire pressure.
2. Check adjustment of front wheel bearings,
Note 5a.
3. Check trueness and tracking of front and rear
wheels.
4. Check front and rear standing heights, Note 6.
5. Check condition of spherical joints and all
bushings, Note 14.
6. Check for looseness in steering gear and
connections.
7. Check caster and camber, Notes 3c and 3d.
8. Check toe-in, Note 3e, and straight ahead
position of steering wheel.
b. Measuring Methods
All wheel alignment equipment manufacturers
provide detailed instructions for checking wheel
alignment with their alignment equipment. These
instructions should be carefully followed.
In addition to the manufacturer's instructions,
be sure to observe the following recommendations:
1. Check to see that the car is at curb weight
(full fuel tank., spare tire, jack, no passengers).
2. Inflate tires to proper pressure.
3. Raise front end of car and check runout of
each tire. Mark the spot where maximum runout
occurs.
4. Place the maximum runout either to the front
or rear. (This neutralizes the effect of runout on
caster or camber). Lower front end of car.
5. Move bumper up and down to normalize the
front spring height.
6. Check caster and camber, Fig. 4-5.
c. Caster Adjustment
Caster is adjusted by turning the lock nuts on
the forward ends of the tie-struts at the frame
front cross member, Fig. 4-6. To gain access to
the lock nuts, remove the air deflector at the
bottom of the radiator. Adjustment is made from
under car.
