3A-4 FRONT END ALIGNMENT
TOE ADJUSTMENT
Check
1) Place the vehicle on levelled ground and with the front wheels
along the vehicle length.
2) Measure the actual length (B) at height (A), with the
appropriate meter and signalize on the tyre the measuring
points.
3) Displace the vehicle towards the back in such way that the
wheels rotate 180°and proceed to measure length (C) using
the same measuring points with the appropriate meter.
4) Subtract lengths (C)-(B), the resulting value must be
somewhere between the maximum and the minimum
specified values:
Minimum Maximum
Toe value
5) If the result is not satisfactory, adjust convergence

6) Loose the counter nuts (1) which fix tie-rod ends (2) to the tie
rod (3) connecting the wheels.
7) Turn the tie rod (3) upwards to open the wheel front parts and
downwards to close them; correcting thus simultaneously
lengths (B) and (C). Repeat this operation until the toe
reaches a value between the maximum and minimum limits.

Toe value
8) Once adjusted tighten nuts (1).
9) Move the vehicle, to and fro, a few meters, while moving the
steering wheel to settle the tie-rod ends and check again for
toe.
NOTE:
If toe has been corrected, the steering wheel setting
will be badly positioned and the right and left rotation
of the steering wheel altered.
10)Balance accordingly the steering wheel rotation towards the
right and towards the left acting on the steering rod (4) and
put right the steering wheel again if necessary (see 3C-4).
