Some brake pads contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
- Raise and safely support the vehicle. Remove the wheel assembly. Remove the dust cap.
- Remove the cotter pin, nut and outer roller bearing assembly from the hub. Remove the brake rotor/hub from the spindle.
- Pry out the inner bearing lip seal and remove the inner bearing assembly.
- Wash all parts in a cleaning solvent and dry with compressed air. Do NOT allow the bearing to turn while dry with compressed air.
- Check the bearings for pitting or scoring. Also check for smooth rotation and lack of noise.
- Thoroughly lubricate the bearings with new "High Temperature" wheel bearing lubricant.
- Apply a light coat of lubricant to the spindle and inside surface of the hub.
- Place the inner bearing in the race of the hub and install a new grease seal. Do not allow the seal to twist in the bore.
- Install the hub assembly on the spindle.
- Install the outer wheel bearing, washer and adjust nut.
- To adjust the wheel bearings, torque the nut to 22 ft. lbs. (30 Nm) while turning the hub, back off the nut completely and then tighten finger tight. If the slot in the nut is not aligned with the spindle, tighten only enough to align.
- Install a new cotter pin and bend over. Install the dust cap on the hub.
- Install the brake caliper and support assembly.
- Install the wheel assembly.
- With the wheel raised, remove the hub cap and dust cap and then remove the cotter pin and nut retainer from the end of the spindle.
- While rotating the wheel, tighten the spindle nut to 22 ft. lbs.
- Turn the hub 23 turns and loosen the nut just enough so it can be turned by hand.
- Turn the nut all the way hand tight and check to be sure the hub has no freeplay.
- Measure the starting torque by pulling a wheel hub stud with a pull scale. Tighten the spindle nut so the pull scale reads 1.12.6 lbs. (0.51.2 lbs.). When the hub begins to rotate.
Make sure the brake pads are not in contact with the drum when measuring rotating torque.
- Install the nut retainer, new cotter pin, dust cap and hub cap.
