REMOVAL & INSTALLATION
Front
R-Series
and C-Series
(see Figure 1)
-
Remove the brake caliper as previously outlined.
-
Remove the outer wheel bearing.
-
Remove the rotor from the spindle.
-
Reverse procedure to install. Adjust the bearings.
Fig. 1: Remove the wheel and outer wheel bearing so that the
rotor can be removed from the vehicle
V-Series
Before starting, you'll need a special wheel bearing nut socket for
your1/2inch drive
ratchet. These sockets are available through auto parts stores and
catalogs. You can't do this job properly without it.
-
Raise and support the front end on jackstands.
-
Remove the wheels.
-
Remove the hubs.
-
Wipe the inside of the hub to remove as much grease as possible.
-
Using your bearing nut socket, remove the locknut from the
spindle.
-
With the locknut off you'll be able to see the locking ring on the
adjusting nut. Remove the locking ring. A tool such as a dental pick
will make this easier.
-
Using the special socket, remove the bearing adjusting nut.
You'll notice that the adjusting nut and the locknut are almost
identical. The difference is, the adjusting nut has a small pin on one
side which indexes with a hole in the locking ring. DO NOT CONFUSE THE
TWO NUTS!
-
Dismount the brake caliper and suspend it out of the way, without
disconnecting the brake line.
-
Pull the hub off of the spindle. The outer bearing will tend to
fall out as soon as it clears the spindle, so have a hand ready to catch
it.
The minimum wear thickness, 1.215 in. (30.86mm), is cast into
each disc hub. This is a minimum wear dimension and not a refinish
dimension. If the thickness of the disc after refinishing will be 1.230
in. (31.2mm) or less, it must be replaced. Refinishing is required
whenever the disc surface shows scoring or severe rust scale. Scoring
not deeper than 0.015 in. (0.38mm) in depth can be corrected by
refinishing.
Some discs have an anti-squeal groove. This should not be mistaken
for scoring.
To install:
-
Carefully place the hub assembly on the spindle. Take care to
avoid damaging the seal on the spindle threads. Make sure the hub is all
the way on the spindle.
-
Place the outer bearing on the spindle and slide it into place in
its race.
-
Thread the adjusting nut on the spindle until it contacts the
outer bearing.
WARNING
Make sure you are using the adjusting nut. Remember, it has a
small pin on one side. That pin must face outwards, towards you!
-
Using the special socket and the torque wrench:
-
Tighten the adjusting nut to 50 ft. lbs. (68 Nm) while rotating
the hub.
-
Back off the adjusting nut until it is loose.
-
While rotating the hub, tighten the adjusting nut to 35 ft. lbs.
(47 Nm) for automatic locking hubs or 50 ft. lbs. (68 Nm) for manual
locking hubs.
-
Back off the adjusting nut
1
/
4
to
3
/
8
of a turn for automatic hubs or
1
/
4
turn for manual hubs.
-
Coat the locking ring with wheel bearing grease. Place the locking
ring on the spindle. There is a tab on the inner diameter of the ring
which must fit in the slot on the top of the spindle. Slide the locking
ring in until it contacts the adjusting nut. The pin on the adjusting
nut must enter one of the holes in the locking ring. You can tell that
the locking ring is seated properly when you see the grease on the ring
get pushed out of one of the holes by the pin, and the ring does not
rock from side-to-side when you press on either side with your finger.
If the locking ring and pin don't index, take note of how far off they
are, pull the ring off the spindle and turn the nut, either by hand or
with the socket, just enough for a good fit. Try the locking ring again.
-
When the locking ring engages the adjusting nut pin properly, your
bearing adjustment is set. Thread the locknut onto the spindle until it
contacts the locking ring.
-
Tighten the locknut to
at least
160 ft. lbs. (217 Nm). This locknut ensures that the
locking ring and adjusting nut don't move. Over-tightening the locknut
has no effect on the bearing adjustment.
-
Install the locking hub.
-
Install the caliper and then install the wheel.
K1 and 2-Series
-
Raise and support the front end on jackstands.
-
Remove the wheel.
-
Remove the caliper. Do not disconnect the brake hose from the
caliper. Use a piece of wire to support the caliper, do not let it hang
on the hose.
-
Remove the rotor.
-
Installation is the reverse of removal.
K3-Series
-
Raise and support the front end on jackstands.
-
Remove the wheel.
-
Remove the hub nut and washer. Insert a long drift or dowel
through the vanes in the brake rotor to hold the rotor while loosening
the nut.
-
Using a puller, force the outer end of the axle shaft out of the
hub. Remove the hub/rotor.
To install:
-
Position the shaft in the hub and install the washer and hub nut.
Leave the drift in the rotor vanes and tighten the hub nut to 173 ft.
lbs. (235 Nm).
-
Remove the drift.
-
Install the wheel and lower the vehicle.
Rear
-
Raise and support the rear end on jackstands.
-
Remove the wheel.
-
Remove the axle shaft. Refer to
for this procedure.
-
Using wheel bearing nut wrench, remove the outer lock nut. If
equipped, remove the retaining ring.
-
Remove the lock or key washer.
-
Remove the bearing adjusting nut and washer.
-
Remove the hub and rotor assembly
To install:
-
Install the hub and rotor assembly making sure the bearings and
the oil seal are positioned properly.
-
Apply alight coating of high melting point wheel bearing lubricant
to the contact surfaces outside diameter of the axle housing tube.
-
Install the washer making sure the tang is engaged in the keyway.
-
Install the bearing adjusting nut and tighten as follows:
-
Tighten the nut to 50 ft. lbs. (68 Nm) while turning the hub.
-
Back off the nut and retighten to 30-40 ft. lbs. (40-54 Nm) while
rotating the hub.
-
Back the nut off 135-150°.
-
Install the lockwasher and the locknut. Bend one ear of the
lockwasher over the inner nut a minimum of 30° and one ear of the
lockwasher over the outer nut a minimum of 60°.
-
Tighten the nut to 65 ft. lbs. (88 Nm).
-
Install the axle shaft, the tire and wheel assembly and lower the
vehicle.
Hope this helped.
after taking the whell off i removed the caliper and then had to remove the hub locking housing and mechanism, after removing these parts I did not see the retaining bolt on the rotor
