INTRODUCTION
The first step in diagnosing any driveability problem is
verifying the customer's complaint with a test drive under the
conditions the problem reportedly occurred. Before entering self-
diagnostics, perform a careful and complete visual inspection. Most
transmission control problems result from mechanical breakdowns or
poor electrical connections.
DESCRIPTION
Page 357 of 1691
ROTOR
CAUTION: DO NOT allow caliper to hang by brake hose.
Inspection
1) Raise and support vehicle. Remove wheels. On Dakota 4WD,
reinstall and tighten lug nuts to secure rotor. On Dakota 2WD, Ram
Pickup and Ram Van, remove dust cap, and temporarily adjust wheel
bearings to zero end play.
2) On all models, mount dial indicator on steering arm, with
plunger contacting rotor about 1" (25 mm) from edge of rotor. Slowly
rotate rotor, and note lateral runout. Lateral runout on either side
of rotor should not exceed specification. See DISC BRAKE
SPECIFICATIONS.
3) On Dakota, check runout of hub face if runout exceeds
specification. Before removing rotor, make a chalk mark across rotor
and one wheel stud. Make mark on high side of runout.
4) Remove rotor from hub. Install dial indicator on steering
arm, with stem contacting hub face near outer diameter. Place dial
indicator stem outside stud circle but inside chamfer on hub rim. If
runout exceeds specification See DISC BRAKE SPECIFICATIONS. Hub must
be replaced.
5) If hub runout is within specification, install rotor on
hub with chalk marks 180 degrees apart. Install wheel lug nuts, and
recheck rotor runout. If runout is not within specification, resurface
or replace rotor.
6) On all models, measure rotor parallelism. To measure
parallelism, measure rotor thickness with micrometer at 12 equal
points around rotor radius approximately 1" (25 mm) from edge of
rotor. If thickness varies more than parallelism specification,
resurface or replace rotor. See DISC BRAKE SPECIFICATIONS.
Removal (Dakota 2WD, Ram Pickup 2WD (5 Studs), & Ram Van)
Raise and support vehicle. Remove wheels. Remove brake
caliper from adapter. Support caliper aside. Remove grease cap, cotter
pin, nut lock, nut, thrust washer and outer wheel bearing. Pull rotor
assembly off spindle.
Installation
1) Slide rotor assembly into position on spindle. Pack and
install outer wheel bearing, thrust washer and nut. While rotating
rotor and hub assembly, tighten wheel bearing nut to specification.
See TORQUE SPECIFICATIONS table.
2) Back off nut to release preload. Retighten nut finger
tight. Install nut lock and cotter pin. Coat inside of cap with
grease, and install cap. To complete installation, reverse removal
procedure.
Removal (Ram Pickup With Tapered Bearings)
1) Raise and support vehicle. Remove wheel. Remove brake
caliper and adapter. Support caliper aside. Remove grease cap and
driving hub snap ring. Remove drive hub and spacer.
2) On models with removable adapter hub, remove hub from
rotor. On models with one-piece hub and rotor assembly, remove grease
cap, cotter pin and bearing adjuster nut. Remove thrust washer and
outer wheel bearing. Remove rotor and hub assembly from spindle.
Installation
1) Apply liberal coat of wheel bearing grease to spindle.
Install hub and rotor on spindle. Pack and install outer bearing.
Install thrust washer and bearing adjuster nut. Tighten nut only
enough to remove end play at his time.
2) Install caliper. DO NOT seat caliper pistons and brake
