front tire pressures are equal.
3. The
frollt tires should show a mold part· line which coincides w ith the centerline of
the tire. If the c enterline of the tire is not readily visible, then the wheel can be raised
off the ground, spun and marked at the approximate centerline location.

1. Loosen both tie rod jam nuts.
2.
Turn the tie rod in or out of the ball joints as required. Retighten the jam nuts when
correct toe in is obtained . One ball joint has left hand threads and the other right hand
so it is unnecessary to disconnect it from the king pin lugs. Turning the joints off the
tie
rod decreases the toe in. Turning the joints on the tie rod increases the toe in.
