S • • I I . REAR SOSPENSIQM HMD AXLE — —
wrench to measure the pinion bearing preload. Ro­
tate the pinion shaft several times with the torque
wrench. Note the indicated torque as the wrench is
moved through several revolutions.
This measurement important because, bear­
ing preload torque must b e ' carefully re-ad­
justed after t h e n e w seal i s installed.
(c) Hold yoke with Holder 6719 and remove the
pinion shaft nut and Belleville washer.
(7) Remove the yoke with Remover C-452 (Fig. 8).

INSTALLATION
(1) Inspect splines on pinion shaft for burrs or
wear, remove any burrs and clean the shaft.
(2) Inspect the pinion yoke for cracks, worn splines
and worn seal contact surface. Repair or replace the
yoke as necessary.
The outer perimeter of the seal is pre-coated
with a special sealant additional sealant is not
required.
(3) Install pinion shaft seal with Installer C-4109A
and Handle C-4735. Seal is correctly installed when
seal flange contacts face of differential housing
flange.
(4) Install yoke on pinion shaft with the reference
marks aligned.
(5) Seat the yoke on pinion shaft with Installer
W-162D and Holder 6719 (Fig. 10).

(6) Remove tools and install the Belleville washer.
The convex side of the washer must face outward.
(7) Hold yoke with Holder 6719 and tighten the
shaft nut to 285 N-m (210 ft. lbs.) torque (Fig. 11).
Rotate pinion shaft several complete revolutions to
ensure the bearing rollers are seated.
CAUTION: Never loosen the pinion gear nut to de­
crease the pinion gear bearing preload torque. If the
specified preload torque is exceeded, a new col­
lapsible spacer must be installed. The torque se­
quence will have to be repeated.
(8) Continue tightening and measuring bearing
preload torque until the torque is the same as origi­
nal measurement. The bearing preload torque
should never exceed 1 N-m (10 in. lbs.) more
than original value.
The bearing preload torque should be con­
stant during a complete revolution of the pin-
