6 Testing & Final Assembly

6.3 Testing the Air Locker Actuation

To test that your air system, electrical system, and your Air Locker

differential is functioning correctly:

c Support the vehicle such that the wheels are free to rotate (e.g., on

axle stands, a chassis hoist, etc.)

c Leave the parking brake off, the transmission in neutral, and the Air

Locker switch ‘OFF’.

c Turn the ignition to the ‘ON’ position (leaving the motor off). The

large illuminating symbol on the Air Locker switch cover should be

‘OFF’.

c Turn the compressor (or alternate air source) on to charge the air

supply up to its maximum pressure.

c While supporting the drive shaft flange, rotate one wheel by hand.

c The wheel should rotate freely and the opposite wheel should be

turning in the opposite direction without any resistance or

mechanical noise from within the differential.

c Turn the Air Locker switch to the ‘ON’ position. The illuminated

symbol on the switch cover should light up.

c Rotate the same wheel again.

c Both wheels should rotate together.

c Turn the switch off again.

c Rotate the same wheel.

c The wheels should again rotate in opposite directions.

6.4 Re-Sealing & Filling the Differential

NOTE : Consult the ARB Air Locker Operating & Service

Manual for recommendations on differential lubricant

specifications.

c Replace the differential cover using gasket sealant or a new

standard differential cover gasket for your make of vehicle.

c Refill the differential until level with the filler hole.

c Rotate the differential center 2 full turns.

c Check the oil level and add oil if necessary.

c Replace filler plug (apply thread sealant to filler plug before

inserting if it is a threaded type plug).

c Wipe differential housing clean of any oil or grease which may

collect dirt or other abrasive particles.
