The required preload is equal to amount re­
corded during removal pirns 0.56 N-m (5 in. lbs.).
The used bearing preload torque must never
exceed 2.25 N-m (20 in. lbs.)
(6) Use Flange Holder 6719 to retain the yoke and
shaft (Fig. 11). Tighten the shaft nut in very small
increments.

(7) Continue tightening the shaft nut in small in­
crements until the correct bearing preload torque is
attained. Tighten the pinion shaft nut to
292 to 427 N-m (215 to 315 ft. lbs.) torque.
(8) Align the installation reference marks and at­
tach the propeller shaft to the yoke.
(9) Add gear lubricant to the differential housing if
necessary.
(10) Install wheel and tire assemblies

REMOVAL
(1) Remove the axle shaft, refer to the removal
procedure.
(2) Remove the nut lock and adjustment nut.
(3) Remove drum and hub. The outer wheel bear­
ing will slide of with the hub.

Remove inner and outer bearings.
CLEANING AND INSPECTION
(1) Thoroughly clean both wheel bearings and inte­
rior of the hub. Remove all of the residual lubricant.
(2) To clean the bearings:
• Soak them in an appropriate cleaning solvent
© Strike the flat of each bearing against a hardwood
block several times
• Flush bearing between strikes
® Repeat the procedure above until each bearing is
clean
© Dry the bearings with compressed air but do not
spin them
(3) After cleaning, apply engine oil to each bearing.
(4) Rotate each bearing slowly while applying
downward force. Examine the rollers for pitting and
roughness. Replace worn or otherwise defective bear­
ings. If a bearing has pitted or has rough surfaced
rollers replace bearing.Always replace bearing
cone and cup as a set.
