PINION SHAFT SEAL
(1) Raise and support the vehicle.
(2) Remove wheel and tire assemblies.
(3) Remove brake rotors and calipers. Refer to
Group 5, Brakes, for proper procedures.
(4) Mark the propeller shaft and pinion yoke for
(5) Remove the propeller shaft from the yoke.
(6) Rotate the pinion gear three or four times.
(7) Measure the amount of torque necessary to
rotate the pinion gear with a (in. lbs.) dial-type
torque wrench. Record the torque reading for installation
(8) Using Holder 6958 to hold the pinion yoke,
remove the pinion nut and washer.
(9) Use Remover C-452 and Wrench C-3281 to
remove the pinion yoke
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with Installer C-3972-A
and Handle C-4171
(2) Install yoke on the pinion gear
Install the pinion washer and a new nut on the
pinion gear. Tighten the nut only enough to
remove the shaft end play.
(4) Rotate the pinion shaft using a (in. lbs.) torque
wrench. Rotating torque should be equal to the reading
recorded during removal, plus an additional 0.56
N·m (5 in. lbs.)
(5) If the rotating torque is low, use Holder 6958 to
hold the pinion yoke
, and tighten the pinion
shaft nut in 6.8 N·m (5 ft. lbs.) increments until
proper rotating torque is achieved.
CAUTION: If the maximum tightening torque is
reached prior to reaching the required rotating
torque, the collapsible spacer may have been damaged.
Replace the collapsible spacer.
(6) Align the installation reference marks on the
propeller shaft and yoke and install the propeller
