(5) Rotate the pinion gear three or four times.
Make sure brakes are not dragging during this
procedure.
(6) Measure the amount of torque necessary to ro­
tate the pinion gear with a torque wrench. Note the
torque for installation reference. This must be
known to properly adjust t h e pinion gear bear­
ing preload torque after seal installation.
(7) Remove the pinion yoke nut and washer. Use
Remover C-452 and Holder C-3281 to remove the
pinion yoke (Fig. 8).
(8) Mark the positions of the yoke and pinion gear

INSTALLATION
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal Installer D-163.
(2) Align the installation reference marks and in­
stall yoke on pinion shaft with Installer C-3718 (Fig.
10).
(3) Install washer with concave surface against the
yoke. Install new nut on the pinion gear. Tighten
the nut to 292 N-m (215 ft. lbs.) torque to re­
move the shaft end play.
CAUTION: Exercise care during the bearing preload
torque adjustment. Do not over-tighten, or loosen
and then re-tighten the nut. Do not exceed the bear­
ing preload torque. The collapsible preload spacer
on the pinion shaft will have to be replaced. The
bearing preload torque will be re-adjusted after­
ward.
(4) Install a socket and inch-pound torque wrench
on the pinion nut.
(5) Rotate the shaft with the torque wrench and
note the torque.
