Toe-In
1. Delermine the wheel toe-in from the alignment
equipment.
2. Change the length of both tie rod sleeves to affect a toe
change.
Toe-in can be increased or decreased by changing the
length of the tie rods. A threaded sleeve is provided for this
purpose.
When the tie rods are mounted ahead of the steering
knuckle they must be decreased in length in order to
increase toe-in. When the tie rods are mounted behind the
steering knuckle they must be lengthened in order to
increase toe-in.
See Section 3B for proper tie rod clamp orientation and
positioning.
