procedure to synchronize the
steering.
Four Wheel Steer Indexing Procedure
1. With the steering select switch (Fig. 10– 87) in the
four wheel steer position, turn the steering wheel fully
left.
2. While holding the steering wheel fully left, toggle the
steer select switch to the front wheel steer position.
3. Steer the front wheels back to center.
4. Toggle the steer select switch back to four wheel
steer position.
5. Turn the steering wheel fully left.
6. Toggle the steering select switch back to the front
wheel steering position.
7. Steer the front wheels fully left.
8. Toggle the switch to the four wheel steer position and
return to center.
The vehicle should now be properly indexed in four wheel

This three-position switch is a single-pole, double throw
toggle switch that has three positions (Fig. 10– 87 and
Fig. 10– 88). It has a multiple-connector plug on its under-
side that connects to the cab wiring harness. Wiring from
the plug connects the switch with power from the fuse
panel bus bar, and to the operators display panel and the
steering select solenoids on the vehicle.
