Inter Axle Speed Sensor
Disassemble and Overhaul Inter-Axle Speed Sensor
Disassemble
The design of the drive axle sensor allows replacement of sev-
eral individual components without disassembling the com-
plete sensor system. For example:
• The differential bearing adjuster does not need to be
removed in order to replace any other component.
• The sensor and rotor can be replaced without
removing or replacing the plated connector.
At every stage of drive axle service, try to isolate the problem
to specific components in order to avoid unnecessary disas-
sembly.
Procedure -
1. Disconnect two wires from sensor terminals.
2. Carefully inspect wires and connector. If connector
is intact and if there is no prior indication that con-
nectors and wires require replacement, do not
unscrew plated connector. The sensor may be
replaced without replacing connector and wire.
3. Remove four screws from face of sensor.
4. Remove sensor from differential bearing adjuster.
Overhaul
Note: If plated connector was damaged during axle disassem-
bly or if there is indication of a wiring fault, the connec-
tor assembly must be replaced.
There are two different connectors with two different lengths
of terminal wires. See Inter-Axle Speed Sensor Service Man-
ual AXSM-0034.
If sensor assembly is to be replaced, install new sensor before
finishing installation of new connector. The final position of
the sensor terminals must be fixed before wires can be sealed
in place.
To install new connector:
1. Clean threaded hole in carrier and wire path to allow
proper seal for new connector. (Male threads on the
new connector have microencapsulated Loctite).
2. Insert connector and torque to 20–28 lbs.ft. (27–38
N•m).
3. Route wires to the sensor location.
