FRONT SUSPENSION 12 - 15
NOTE: Wheels and tires should be balanced statically
and dynamically.
2. Weak front spring.
3. Front shock absorbers not operating correctly.
4. Lack of lubrication in front suspension.
5. Front stabilizer not positioned correctly.
FRONT WHEEL
ALIGNMENT
All of the five factors of front wheel alignment are
inter-related, but each has a specific purpose. These control
the front wheels and steering under varying conditions of
weight and speed.
Should one of the angles get out of position, the relation-
ship is destroyed. Each angle depends upon the proper
setting of the others if the front wheels are to lead properly.
In making corrections to front wheel alignment, or
installing new front wheel suspension parts, all five angles
in both front wheels should be checked in the following
order:
PIVOT PIN INCLINATION
Pivot Pin Inclination is the inward tilt of the steering
spindle pivot pin at the top.
CASTER
Caster is the backward tilt of the steering spindle pivot pin
usually measured in degrees.
CAMBER
Camber is the outward tilt of the front wheels at the top
and usually measured in inches or degrees.
TOE -IN
Toe-In is the drawing together of the front wheels at the
front.
STEERING GEOMETRY
Steering Geometry or toe-out on turns is controlled by the
movement and angularity of the tie rods.
GENERAL INSPECTION
Before checking the alignment of the front wheels, the
following operations should be performed in the order list-
ed. A successful alignment job cannot be accomplished
unless these inspection operations are performed. Should
inspection reveal the necessity for removing, installing, or
adjusting any part of the front wheel suspension, or steering,
prior to aligning the front wheels, complete instructions will
be found in the respective sections of the manual.
1. Inflate all tires to recommended pressure.
2. Check condition of tires (blowout patches, thin treads,
vulcanizing, etc.). Changing the direction of tire rotation is
recommended.
3. Wheel and tire turn-out, (wobble) or eccentricity.
4. Brakes for dragging.
5. Wheel balance.
6. Front wheel bearing adjustment.
7. Coil spring height.
8. King pin and bushing clearance.
9. Upper and lower support arm bushings.
10. Steering gear, adjusting points.
11. Shock absorber control.
12. Rear-springs and "U" bolts.
When checking front wheel alignment, the car should be
placed on a level floor. The car should be empty, and any
luggage or load should be removed from the trunk compart-
ment.
NOTE: Always rock the car back and forth several times
and allow it to settle
.
