Brake Rotor (Disc) - REMOVAL & INSTALLATION

1. Loosen the wheel lug nuts.
   
2. Jack up the front of the vehicle and support on jackstands.
   
3. Remove the wheel and tire.
   
4. Remove the brake caliper assembly as described earlier in this section, but do not disconnect the brake hose.
   
5. Suspend the caliper assembly by a piece of wire. Do not allow it to hang by the brake hose.
   
6. Follow the procedure given under wheel bearing removal in Suspension and Steering for models with manual and automatic locking hubs (lines down).

New rotor assemblies come protected with an anti-rust coating which should be removed with denatured alcohol or degreaser. New hubs must be packed with EP wheel bearing grease.

6. Remove the inboard brake pad.
7. Remove the axle shaft nut and washer.
8. Through the hole provided in the rotor, remove the six retainer bolts.
9. Position pull C-4358, or equivalent, over the wheel lugs and install the lug nuts. Tighten the main screw of the puller to remove the hub, bearings, retainer and outer seal as an assembly.
10. Insert a prybar through the U-joint and wedge the shaft inward as far as it will go. Make sure that it is wedged securely and can't be moved.
11. Install the hub, rotor and bearing assembly and tighten the retainer bolts to 30 ft. lbs. (40 Nm) in a crisscross pattern.

15. Using the lube fitting, fill the knuckle with NLGI, Grade 2, multi-purpose EP grease until the grease is seen flowing through the inner seal. Fig. 5: Lubrication fitting location on the rotor top hat
    
    
16. Install the inner brake pad and caliper (see Section 9).
17. Install the wheels and tighten the lug nuts to 110 ft. lbs. (150 Nm).

The Constant Velocity (CV) joints are located on the inner and outer edges of the axle shaft. The axle shaft runs through the hub and bearing in the spindle.

does noise seem to increase as speed increases if so most likely is the hub bearing it,s a seal bearing and hub flange assembly good thing is you won,t have to press any bearings in and out but you will have to dig deep in the pocket it generally comes all together and with abs sensor it can be removed after removing brake caliper, pads ,caliper mount and rotor tehn remove nut at end of axle if you look on back side of the spindle you will see three or four bolts remove them and hub assembly should come off install in reverse order,remember to disconnect abs sensor on old and reconnect new

1. Raise and safely support the vehicle.
2. Remove the wheel and tire assembly.
3. Remove the caliper from the spindle and rotor, but do not disconnect the brake hose. Suspend the caliper inside the fender housing with a length of wire. Do not let the caliper hang by the brake hose.
4. Remove the grease cap from the hub and remove the cotter pin, nut retainer and adjusting nut.
5. Grasp the hub/rotor assembly and pull it out far enough to loosen the washer and outer wheel bearing. Push the hub/rotor assembly back onto the spindle and remove the washer and outer wheel bearing.
6. Remove the hub/rotor assembly from the spindle.
7. Inspect the rotor for scoring and wear. Replace or machine as necessary. If machining, observe the minimum thickness specification.

1. If the rotor is being replaced, remove the protective coating from the new rotor with brake cleaner. Pack a new set of bearings with high-temperature wheel bearing grease and install the inner roller bearing in the inner cup. Pack grease lightly between the lips of a new seal and install the seal, using a seal installer.
2. If the original rotor is being installed, make sure the grease in the hub is clean and adequate, the inner bearing and grease seal are lubricated and in good condition, and the rotor braking surfaces are clean.
3. Install the hub/rotor assembly on the spindle. Keep the assembly centered on the spindle to prevent damage to the grease seal or spindle threads.
4. Install the outer wheel bearing, washer and adjusting nut. Adjust the wheel bearings according to the procedure in , then install the nut retainer, cotter pin and grease cap.

you do have to dissasemble the hubs because the rotors bolt on to them. if it is two wheel drive take the center caps off of hubs remove the spindle nuts and bearings pull complete hub assembly off and unbolt rotor from hub. if it is four wheel drive you will have to remove the lockout assembly be careful not to loose any parts from this it won't work when put back together.

it should come out once you have disconnected:Brakes,strut,ball joint.tire rod end,cv joint!if it is not put the cv joint nut back on until safe enough to give it a tap with hammer to knock back & out shaft this should come as one piece HUB the bearing is pressed in! better to change whole HUB good luck this hopefully helped you out!

The brake rotor needs to be removed, drive shaft nut in center of hub then 3 bolts hold the hub assembly to spindle from back side. if it has abs unplug it then some work will need to be done with a hammer and chisel to work the bearing out of spindle and axle shaft from bearing
