| The front hub and bearing assembly must be
removed to replace the brake rotor, figure 1. If
the vehicle is serviced incorrectly, the bearing
may be damaged. A common removal method
that can result in bearing damage is using a
slide hammer to separate the hub from the
bearing. The effects of a slide hammer can be
damaging to the bearing and bearing seal. |
 |
| To avoid damaging the bearing and seal the
hub and rotor should be removed as an
assembly from the back side of the knuckle.
The recommended method to service
these vehicles is as follows: |
• Separate the outer tie rod from the steering
knuckle using a suitable taper breaking tool,
figure 2.
• Remove the CV axle nut, figure 2.
• Separate the lower ball joint from the lower
control arm.
• Remove the caliper and caliper mounting
bracket. Support the caliper so no stress is
placed on the brake hose. |
 |
• Separate the outer CV joint from the hub,
figure 3.
• Remove the four bolts holding the hub
assembly to the knuckle, figure 3.
• Install four 10mm x 1.25 bolts that are
approximately 60mm long in place of the
bolts just removed. Thread these bolts in until
they lightly bottom out. Use graded bolts if
available. |
 |
| • Use a blunt tip or smoothing hammer attachment
in an air chisel to vibrate the bolt heads
and work the assembly free. The rotor and hub will walk out of the knuckle without damaging the bearing, figure 4. |
 |
| When the hub and rotor are removed from
the vehicle, the hub assembly can be easily
removed for rotor replacement, figure 5.
Note: The hub and bearing do not need to be
separated. |
 |
The new rotor does not require machining; it
is ready to install right out of the box.
To re-install, reverse the previous procedure
and use the torque specifications recommended below.
All torque specifications are in foot pounds. |
|
Flange bolts (hub to disc) 40
Flange bolts (steering knuckle to hub) 33
Caliper bracket mounting bolt 81
Lower ball joint 37-44*
Outer tie rod 32*
Axle (CV) nut 184
Wheel lug nuts 80

*If the cotter pin hole does not line up with a
slot in the castellated nut, tighten the nut to
the next slot. Do not back off the nut to align
the pin hole. |
