(5) If reusable, remove the engine oil from each
bearing. Pack each bearing with multi-purpose
NLGI, grade 2, EP-type lubricant.
Ensure that lubricant is forced into all the
cavities between the bearing cage and rollers.
INSTALLATION
(1) If a bearing and cup must be replaced, remove
the cup from the hub bore. Use a brass drift or an
appropriate removal tool to tap out the cup.
(2) Install the replacement bearing cup(s) with an
appropriate installation tool.
(3) Apply lubricant to surface area of the hub bore.
Install the inner wheel bearing in the hub. Install a
replacement bearing seal with an appropriate seal in­
stallation tool.
(4) Inspect the bearing and seal contact surfaces
on the axle for burrs and/or roughness.
(5) Remove all the rough contact surfaces from the
axle. Apply a coating of multi-purpose NLGI, grade 2,
EP-type lubricant to the axle.
CAUTION: Use care to prevent the inner wheel bear­
ing and bearing seal from contacting the axle
threads during installation.
(6) Carefully slide the hub onto the axle and in­
stall outer wheel bearing.
(7) Install adjustment nut and tighten to 163-190
N-m (120-140 ft. lbs.) torque while rotating the
wheel.
(8) Back off adjustment nut 1/8 to 1/3 of a turn to
provide 0.001-inch to 0.010-inch wheel bearing end
play.
(9) Tap locking wedge into the spindle keyway and
adjustment nut.
(10) Install the axle shaft, refer to the installation
procedure.
DIFFERENTIAL DISASSEMBLY
MEMOWALmiSASSEmBLW
Remove RWAL/ABS brake sensor hold-down
bolt and pull the sensor from the differential
housing. The sensor must be removed to pre­
vent damage when disassembling or assembling
the differential components.
(1) Note reference letters located on bearing caps
and housing machined sealing surface (Fig. 12). Re­
move the differential bearing caps.
(2) Position Spreader W-129B with the tool dowel
pins seated in the locating holes (Fig. 13). Install the
holddown clamps and tighten the tool turnbuckle fin­
ger-tight.
(3) Install a pilot stud at the left side of the differ­
ential housing. Attach Dial Indicator to housing pilot
stud. Load the indicator plunger against the opposite
side of the housing (Fig. 13) and zero the indicator. -

Fig. 13 Differential Housing Spreader
CAUTION: Do not spread over 0.38 mm (0.015 in). If
the housing is over-separated, it could be distorted
or damaged.
(4) Separate the housing enough to remove the
case from the housing. Separate housing a maxi­
mum distance of 0.38 mm (0.015 in) with the
spreader tool. Measure the distance with the dial
indicator (Fig. 13).
(5) Remove the dial indicator.
(6) Pry the differential case loose from the housing.
To prevent damage, pivot on housing with the end of
the pry bar against case.
(7) Remove the case from housing. If they are re­
usable, retain the differential bearing cups and bear­
ings together as matched sets.
(8) Clamp the differential case in a vise equipped
with soft jaws. Remove and discard the ring gear
bolts. Tap the ring gear off with a rawhide or plastic
mallet (Fig. 14).
(9) The exciter ring can be removed with a soft-
faced hammer (Fig. 15). Discard after removal.
