6 Testing & Final Assembly

6.2

Testing the Air Locker Actuation

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

differential is functioning correctly:

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

axle stands, a chassis hoist, etc.)

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

Locker switch ‘OFF’.

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

large illuminating symbol on the Air Locker switch cover should be

‘OFF’.

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

supply up to its maximum pressure.

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

 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.

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

symbol on the switch cover should light up.

 Rotate the same wheel again.

 Both wheels should rotate together.

 Turn the switch off again.

 Rotate the same wheel.

 The wheels should again rotate in opposite directions.

6.3

Re-Sealing & Filling the Differential

NOTE : Consult the ARB Air Locker Operating & Service

Manual for recommendations on differential lubricant

specifications.

 Replace the differential cover using gasket sealant or a new

standard differential cover gasket for your make of vehicle.

 Refill the differential until level with the filler hole.

 Rotate the differential carrier 2 full turns.

 Check the oil level and add oil if necessary.

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

inserting if it is a threaded type plug).

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

collect dirt or other abrasive particles.
