2 Removing the Existing Differential
5
2.1 Vehicle Support
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.
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
Clean around the differential cover flange seal to prevent dirt from
entering the differential.
Position a fluid drain reservoir under the differential.
Remove fluid drain plug to empty all differential oil.
HINT : This is a good time to check for metal particles in
your oil which may indicate a worn bearing or
differential component.
2.3 Removing the Axles & Differential
Disconnect the stub axles from the differential assembly according
to your vehicle’s service manual..
Disconnect the drive shaft from the flange of the drive pinion.
Remove the entire differential assembly from the vehicle.
NOTE : The differential housing is heavy and quite difficult to
handle when covered in oil. Do not drop it!
Secure the assembly to a work bench, and remove the cover plate.
Remove the axle assembly from the side of the differential housing.
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 tube may result in excessive wear and/or failure of your
differential and stub shaft. ARB strongly recommends that you have
your axle assembly inspected for concentricity and straightness before
installing your Air Locker.
