The bearing preload torque should be con­
stant during a complete revolution of the pin­
ion gear. If preload torque varies, this indicates
a binding condition and must be corrected.
(9) The seal replacement is unacceptable i f the fi­
nal nut torque is less than 285 N-m (210 ft. lbs.)
torque.
(10) Install drive shaft with the installation refer­
ence marks aligned. Tighten the U-joint yoke clamp
screws to 19 N-m (14 ft. lbs./170 in. lbs.) torque.
(11) Install the brake drums, and wheel and tire
assemblies.
(12) Check the differential lubricant level and add
i f necessary.
(13) Remove support and lower vehicle.

spring center bolts.
(2) Install the spring clamp bolts and nuts, and
shock absorber lower bolts. Tighten the nuts to the
specified torque.
(3) Connect the parking brake cables.
(4) Connect the brake fluid tube fittings to the
wheel cylinders. Bleed and adjust brakes refer to
