2 Removing the Existing Differential
6
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
HINT : This is a good time to check for metal particles in
your oil, on your drain plug, or in the bottom of the
housing, which may indicate a worn bearing or
differential component.
2.2.1 A IFS Fluid Drain
 Remove any skid plates covering the bottom of the front axle area
and position a fluid drain reservoir under the differential.
 Remove the threaded drain plug and completely drain all differential
oil from the housing.
 Finger-tighten the drain plug back in to prevent drips during the
removal of the axle assembly.
2.2.2 B Live Axle Fluid Drain
 Clean around the differential cover plate seal to prevent dirt from
entering the differential.
 Position a fluid drain reservoir under the differential and loosen all
differential cover plate retaining bolts.
 Gently pry the cover plate away from the differential housing to
completely drain all differential fluid.
 Once drained, remove the differential cover plate.
HINT : It would be a good idea to drill and tap for a tapered oil
drain plug to assist with future oil changes.
