Installation Guide for Steer Axle Deflection Sensors



Exert downward pressure lightly with your fingers on the

non-cable end of the sensor until the A/D reading is between 750 and 1250.



Tighten nut and torque to 30 ft-lbs. If the A/D reading is still in range, proceed to instructions for the final sensor torque.

Final Sensor Torque

4. Tighten both bolts to 60 ft-lbs.

5. Perform a final check of A/D values. If not within range, repeat the steps for altering A/D readings.

6. If you are using the deflection sensor test box to set

A/D values, disconnect the box and connect the deflection sensor cable to the sensor extension cable.

Steer Axle Finishing Touches

1. Slide the connector assembly onto the connector bracket tab mounted on the deflection sensor bracket, by inserting the tab into the grooves on the bottom side of the bracket. Ensure the connector assembly slides completely on the mounting tab.

2. Route the cable coming out of the receptacle portion of the connector assembly so it can be used for a driver’s side hookup or a passenger side hookup.

NOTE: Make sure there is enough slack in the sensor extension cable between the axle and the frame to allow for axle movement.

3.

Driver’s side sensor orientation: Facing toward the rear of the vehicle, route the cable from the connector assembly so it runs to the right of the steer axle sensor assembly

(Fig. 15).

4.

Passenger’s side sensor orientation: Facing toward the rear of the vehicle, route the cable from the connector assembly so it runs to the left of the steer axle sensor assembly (Fig. 16).

5. Mount the cover over the sensor and the sensor brackets so that the sensor cable is completely under the cover. The bracket band clamps should emerge from the cover’s side ports (Fig. 17).The sensor extension cable should emerge from the cover’s end port on whichever side you choose to route the cable.

6. Very loosely install band clamps around the steer axle on both ends of the deflection sensor cover. Ensure that the band clamp on each side circles both the steer axle and the cover flange (Fig. 18). Fig. 19 shows completed installation.

7. Secure the sensor cable to the axle. Run the drive sensor extension cable along the rear of the axle toward the side of the truck (driver’s side or passenger’s side), securing with a band clamp. Place split loom over the band clamp where it crosses over the cable. Secure the cable to the band clamp with nylon ties. See Fig. 20. Use additional 24-inch nylon ties as required to secure the cable to the steer axle.
