TOE-IN
Viewed from above, the wheels should have a certain rela-
tionship to each other, expressed as the difference be-
tween dimensions A and B, measured rim-to-rim at axle
height.
The setting is called toe-in when dimension A is less than
dimension 8. When dimension A is greater than dimen-
sion B, the wheel setting is referred to as toe-out.
Toe-in or toe-out is expressed in inches or millimeters,
being — as stated — the difference between the two mea-
surements A and B. If the wheels are parallel, so that
there is neither toe-in nor toe-out, the difference will be
0.
The toe-in should be 0.08 i 0.04 in. (2 i mm) if the
car is fitted with diagonal tires (5.20 x 15 or 5.60 x 15)
and 0.00 i 0.04 in. (O i mm) if the car is fitted with
radial tires (155 SR 15).
Checking and adjustment
1. Roll the car slowly straight ahead on a level floor and
stop it without using the brakes. Do not move the car
backwards again.
2. Check the measure A using the special measuring rule
78 40 010, between the edges of the rims at axle height.
Make a scribed mark at the measure points. Move the
car forward until the scribed mark comes in axle height
again. Check measure B.
If adjustment is called for, alter the length of the tie-
rods.
3. Back off the lock nut on the outer end of the tie-rod.
ADJUSTMENT OF TOE-l N
1. Lock nut
2. Clamp ring
4 Turn the tie-rod to right or left’ and search until Ob
'nin the right toe-in. . .
E'stezring gears of earlier desrgn. the tie-rod has a key
ri In the later design there is no grip and then the
fie-prod must be turned with a pair of pliers.
NOTE .
If the rubber boot is so tightly clamped that It accom
paines the tie-rod when turned. the clamping ring
must first be slackened.
If the toe-in is correct, and when both wheels are point.
ing straight ahead, the two tie-rods should be of equal
length, or else be so set that the wheels have the same
amount of clearance from fenders and wheel houses when
turned hard right or hard left. Check also that the spokes
of the steering wheel are horizontal when the wheels are
centered. Remember to tighten the tie-rod lock nuts after
adjustment.
CHECKING THE
LENGTH OF A TIE-ROD WITH KEY GRIP
NOTE
After adjustment of to-in, the measurement A for a
tie-rod of the earlier design must on no account ex-
ceed 1.57 in. (40 mm).
For tie-rods opposed to each other, the difference
between the measurements A must not exceed 0.08
in. (2 mm).
