2 Removing the Existing Differential
5
2.1
Vehicle Support
F
Safely secure the vehicle on a hoist. We recommend supporting the
vehicle on a chassis hoist to keep the differential area at a
convenient working height and to leave the wheels and axles free
to be rotated and removed.
F
Once supported off the ground, release the parking brake and
leave the vehicle in neutral. Chock the wheels if necessary.
2.2
Differential Fluid Drain
F
Clean around the differential drain plug to prevent dirt from entering
the differential.
F
Position a fluid drain reservoir under the differential and loosen the
differential drain plug.
F
Completely drain all differential fluid.
HINT : This is a good time to check for metal particles in
your oil and in the bottom of the housing which may
indicate a worn bearing or differential component.
2.3
Removal of the Axles and Differential
IMPORTANT :
Collision damage or heavy off-road use of your vehicle in the past may
have resulted in some degree of bending in the axle. Any misalignment
of the axle tubes may result in excessive wear and/or failure of your
differential and axle shafts. ARB strongly recommends that you have
your axle assembly inspected for concentricity and straightness before
installing your Air Locker.
F
Remove the wheels and brake assembly according to your vehicles
service manual.
F
