(12) Clean the disc brake rotor contact surfaces, if
necessary.
(13) Install the wheel hub/disc brake rotor on the
spindle.
(14) Install the wheel outer bearing, the thrust
washer, and the spindle nut.
(15) Tighten wheel bearing nut to 27-34 N-m (240-
300 in. lbs.) torque while rotating hub/rotor. This will
seat the bearings.
(16) Loosen the nut 1/4 of-a-turn (90°), then
tighten it finger tight.
(17) Position nut lock on the nut with one pair of
slots aligned with the cotter pin hole. Install the cot­
ter pin.
(18) Clean the dust cap and apply wheel bearing
lubricant to the inside surface. Do not fill the dust
cap with lubricant.
(19) Install the dust cap.
(20) Install the disc brake caliper.
(21) Install the wheel/tire. Tighten the wheel lug
nuts to 115 N-m (85 ft. lbs.) torque. Install the wheel
cover.
REAR WHEEL BEARINGS
The rear wheel bearings for vehicles equipped with
a Dana 60, 70 or 80 axle should be cleaned and re­
packed whenever the rear brakes are serviced. Refer
to Group 3, Rear Axles for the service procedure.
BRAKES
The brake fluid level should be inspected when
other underhood service is done (Fig. 4, 5 and 6). If
necessary, add fluid to raise the level to the top of
the indicator window. With disc-brakes, the fluid
level can be expected to fall as the brake pads wear.
However, a low fluid level can also be caused by a
leak, and repair will then be necessary, refer to
Group 5, Brakes for proper service procedures.
FLUID SPECIFICATION
Power brake systems require Mopar Heavy-Duty
Brake Fluid, or an equivalent product identified with
FMVSS No. 116, DOT-3 and SAE J-1703 Standard
designations.
Use brake fluid properly sealed container when
adding fluid to the reservoir. Never use reclaimed
fluid or fluid that does not conform to the DOT/SAE
Standards.
CAUTION: Use of a brake fluid that has a lower ini­
tial boiling point then specified by F M V S S No. 116
or DOT 3 and S A E J1703 could result in sudden
brake failure during hard, prolonged braking.
Do not allow petroleum base fluids to contami­
nate the brake fluid. Seal damage will result.

INSPECTION
(1) Inspect the brake pads and linings for excessive
wear, cracks and broken rivets.
(2) Inspect brake pads and linings for contamina­
tion with brake fluid, axle lubricant and/or other flu­
ids.
(3) Replace the front brake pads and the rear
brake linings if they are worn to within 0.78 mm
(0.031 in) of a rivet head.
