Front Brake Rotors
Models: 1998 Ram 1500 2 wheel
drive BR/BE trucks with RWAL brakes and built:
from 10/16/97 through 10/21/97 (MDH 101620 through 102113) at the
Warren Truck Plant ("S" in the 11th position);
from 10/17/97 through 10/21/97 (MDH 101722 through 102111) at the
St.Louis North plant ("J" in the 11th position).
The front brake rotors on the above may have been made from material
that is out of specification. This may cause cracking around the
wheel mounting area and result in wheel separation. To correct this
problem the rotors must be inspected and replaced if necessary. [when
you see one of these rotors they look like S**T!] Aprox 900 vehicles
1 Brake rotor
1 grease seal
1 cotter pin
A. Inspect Front Brake Rotors
If the date code on ONE or BOTH rotors is 287, Replace the
rotors. If neither rotor has a 287 code, no further action is necessary.
NOTE: If there is no date code or if the date code is illegible, the
rotor must be replaced.
B. Front Brake Rotor Replacement
Raise the vehicle on a hoist. NOTE: do not lock the steering column
so that the front wheels can be turned by hand
Check the date code on the back side of each front rotor through the splash
shield window (Fig 1)
Rotate the caliper rearward off of the rotor and out of the steering knuckle
support ledges (Fig 3).
Secure the caliper to a convenient chassis or suspension component with
a tie wire.
Remove the front tire and wheel assembly
Remove the caliper mounting bolts with a 3/8" hex wrench (Fig 2)
Remove the grease cap that covers the cotter pin and hub nut (Fig 4)
Remove cotter pin (Fig 4)
Remove locknut cage from the wheel bearing adjusting nut and then remove
the adjusting nut, thrust washer, and outer wheel bearing (Fig 4)
Remove the brake rotor assembly from the spindle (Fig 4)
Remove the inner grease seal by gently tapping on the inner bearing with
a wooden dowel. Discard the grease seal (Fig 4)
CAUTION: Do not support the caliper by the brake hose. This can damage
the hose and fittings.
Remove the inner wheel bearing from the rotor assembly (Fig 4). Discard
the rotor assembly.
Repack the wheel bearings with Mopar high temp bearing grease. Apply grease
to the bearing races in the new rotor as well.
Install the inner wheel bearing assembly into the new rotor assembly (fig
Install the provided grease seal onto the new rotor assembly. Use a seal
driver or wooden block to avoid damaging the new seal. (Fig 4)
Apply a liberal coating of bearing grease to the spindle, the interior
of the rotor, the hub seal lip, and the spindle seal surface.
Install the new rotor assembly onto the spindle.
Install the outer wheel bearing, thrust washer, and bearing adjusting nut
(Fig 4). Tighten the nut only enough to remove end play at this time.
CAUTION: Do not use a metal object or excessive force to drive the inner
bearing and grease seal out or bearing damage may result.
Clean the caliper and steering knuckle slide surfaces with a wire brush
Apply a coat of silicone grease to the slide surfaces (Fig 5)
Install the caliper over the rotor and seat it on the steering knuckle
mounting arms (Fig 5)
Start the caliper mounting bolt and tighten them to 38 ft-lbs (51 Nm) (Fig
Repeat steps above for other rotor if needed
Install the wheel and tire assembly(s). Snug the lug nuts but DO NOT tighten
at this time.
Adjust the wheel bearings by rotating the wheel and fully tightening the
bearing adjusting nut to seat the bearings
Loosen and tighten the bearing adjusting nut again while rotating the wheel
Continue rotating the wheel and back off the adjusting nut until the wheel
end play is no more than 0.001" - 0.002" (0.025 - 0.051 mm)
Install the locknut cage on the adjusting nut and then install the provided
cotter pin. The adjusting nut can be tightened slightly to align the cotter
pin holes if necessary. Verify that the wheel bearing adjustment is still
Install the hub nut grease cap
Tighten the wheel lug nuts to 95 ft-lbs (130 Nm)
Repeat for other side if necessary.
Lower the vehicle
Apply the brakes several times to seat the shoes and caliper piston. Do
not move the vehicle until the brake pedal is firm.
NOTE: Cover the bearing and spindle area with a shop towel to avoid
