CHECKING AND ADJUSTING TOE-IN
1. Straighten wheels to vertical position.

3. Turn wheels to straight ahead position.
4. Measure the distance between axle centerline
and tie rod pin centerline (A), Figure 15, on each
tie rod. The difference between axle centerline
should be 0.0 - 0.10 in. (0.0 - 2.5 mm).
5. If the distance is greater than 0.10 in. (2.5 mm)
loosen tie rod nut on one tie rod.
6. Turn the tie rod until the distance between the
tie rod pins is within 0.10 in. (2.5 mm) of the
second tie rod.
7. Measure distance (B), Figure 16, from ground
to center of hub.
8. Lift tires off ground enough to rotate.
9. At height (B), make a mark in center of tread
on rear of each front tire.
