18. ABS Sensor Replacement Procedure

18.1 Sensor Removal

NOTE: ABS sensors MUST match the system. DO NOT mix

sensors from different manufacturers.

1. Manually release the brakes.

2. Remove brake drum assembly as described in Section 4.

3. Disconnect the ABS sensor connector and remove the

sensor from the sensor holder by pulling straight out
(Figure 51).

4. Remove the sensor retaining spring clip, if necessary.

18.2 Sensor Installation

NOTE: Be sure to use the correct spring clip for the sensor

being installed.

1. Install the sensor retaining spring clip, if removed, into

the sensor holder.

2. Install the ABS sensor into the spring clip and sensor

holder. Push the sensor in until it contacts the tone ring
(Figure 52).

3. Connect the ABS sensor connector.

4. Re-install drum using support device such as a drum dolly

jack (Figure 37).

5. Adjust brakes as described in Section 17.

19. Axle Alignment Inspection

NOTE: Alignment can be achieved using an optical device

designed specifically for this purpose. Follow
the instructions in the optical device operating
instructions to align the axles.

1. To manually align the axles attached to your trailer, first

pull the trailer in a straight line for a sufficient distance
to release/clear any binds in the suspension.

NOTE: A straight, unbound suspension is the position of

a suspension during normal operations.

Using the alignment procedures per the suspension
manufactuer’s recommendations, align the axles to the
following specifications.

2. Measure the distance from the king pin to the centerline

of the spindles on each side of the front axle. Dimensions
A and B MUST be equal to within 1/8" (4 mm) (Figure
53, A and B).

3. Measure the distance from the centerline of the spindles

of the front axle to the centerline of the spindles of each
additional axle. Dimension C and D must be equal to
within 1/16" (1 mm) (Figure 53, C and D).
