Removal
(1) Remove rear wheel, drum, and hub as outlined
under Axle Hub-AMC/Jeep Axle.
(2) Disconnect parking brake cable at equalizer.
(3) Disconnect brake line at wheel cylinder and re-
move brake support plate assembly, oil seal, and shims
from axle shaft.
NOTE: If both axle shafts are removed, keep the shims
separated. Axle shaft end play is adjusted on the left
side only.
(4) Remove axle shaft and bearing using tool J-2498
(fig. 2F-20).
CAUTION: On vehicles equipped with a Trac-Lok dif-
ferential, do not rotate the differential gears unless both
axle shafts are in place. If one shaft is removed and
remaining shaft is rotated, the side gear splines will
become misaligned and prevent installation of the re-
placement shaft.
(5) Remove and discard axle shaft inner oil seal.
(6) Remove axle shaft bearing if bearing is worn or
damaged.
NOTE: The bearing is a press-fit on the axle shaft and
must be removed using an arbor press only (fig. 2F-21).
Do not attempt to remove the bearing by any other
method.

fore installation.

ferential side gear splines and insert shaft into gear.

(7) Inspect brake support plate for elongated bolt
holes. Replace support plate if necessary.
NOTE: During assembly, apply a silicone-type sealer
to the axle tube flange and brake support plate mount-
ing area to prevent entry of dust and water.

sembly, and brake support plate. Tighten attaching
bolts to 35 foot-pounds (47 N»m) torque.
