    dont know if you can see this,

    remove the dust cap with a flat chisel or screwdriver,remove snap ring then remove six bolts holding flange to hub.remove flange you may have to tap it a little to get loose

    then you can get to the nut that holds it on, there will be a lock ring that is tabbed over nut bend this back with a screwdriver and nut will come off and rotr/hub assembly will slide off. swap rotor and reinstall

Everything on the lower left in TripleTauto's picture needs to be removed before the rotor will come off, from the outer cap down to the outer race. as pictured. The lock nuts are inside the axle hub assembly. The only way to remove the rotor is to remove the large nuts, which holds the axle hub to the spindle.

The axle hub comes off WITH the rotor.

Please advise if you have any other questions.

Did you get the lock nut inside the rotor/hub off? If not, you need to remove this, it would have been the next step after you removed the flange. Look at tripleauto's great diagram if you need to.

If you did get this off and the rotor/hub seems loose, start tapping on the rotor from behind if you can to release it. Very typical to have some rust build up here on many vehicles, especially if the vehicle's battery ground isn't all that great. (whole other topic)

Spray a little spray lubricant (liquid wrench is the best, but WD-40 will work) around the border where the rotor meets the wheel hub (roughly half-way between the center of the hub and the wheel lugs. You can also spray a little around the base of the lugs themselves. Give that a couple of minutes to penetrate and try to pull the rotor free. If necessary, use a small hammer and tap lightly around the outer edges of the rotor (from behind the rotor and toward you) until it breaks free from the hub. The first time If you couldn't get the rotor to budge, even with the help of the hammer, the penetrating oil should be applied on the sides of the rotor to make it loose.

The "notched nut" is for the CV boot, and not for the rotor. The rotor may be screwed to the hub with big phillips screws, or may just need to be tapped off with a hammer if you are in the rust belt. Either way, make sure the caliper mount is taken off beforehand.

Rotor removal usually requires the removal of two bolts from the back side of the caliper. Get a flashlight, get to where you can see the back of the caliper, and look for bolts that are either torx or allen head, about 1/2 inch in diameter. Sometimes, the bolt heads are covered with plastic caps, so you will have to remove the caps to expose the bolt heads.

Be sure and spread the caliper first before removing, or you will not get the caliper back on with new pads installed.

    You normally do not have to remove the rotor, or the bearing hub, to replace the pads, unless you plan to turn the rotors and the rotor/hub assembly is all in one.

  • Mark Egan Jan 16, 2009

    After you take the dust cap off, your will either see the big nut and cotter key, or you will see a nut cover and cotter key. Either way, take the cotter key out. Remove the nut cover if there is one, and unscrew the nut.

    Hopefully you don't have a locked bearing on the spindle. I had that once, it was a bear to remove.


  • Mark Egan Jan 19, 2009

    Sorry for my delayed reply (if you didn't get the rotor off over the weekend.).

    Have you removed the cotter key and nut that holds the rotor on the spindle yet? If so, then there should be a washer behind the nut, then the outer bearing. Once the washer is removed, you should be able to grab either side of the rotor and pull, first left, then right, and the bearing should pop out at you (and possibly the whole rotor may come off with it.).

    If the rotor will not come off at this point, having done the above, the bearing is likely locked onto the inner bearing, and it's going to take some brute force with a RUBBER mallet to get the rotor off.

    Once you get the rotor off, have it turned to be sure it isn't damaged, and replace both bearings and seal.

How do i change the front wheel bearrings on a 1999 sonoma 2 wheel drive?


The bearing is in the hub.. Here are some instructions for that:
  • The wheel bearing is installed in the wheel hub assembly and is serviced by replacement only.

  • You may need Torx sockets to remove the bearing assembly bolts.


  • Raise and support the front of the vehicle safely using jackstands.

    Remove the tire and wheel assembly.

  • At the wheel hub, remove the cotter pin and retainer, then loosen and remove the castle nut and the thrust washer. In order to hold the hub from turning when loosening the nut, insert a drift through the caliper and into the rotor vanes. Remove the brake caliper and support it aside using wire or a coat hanger. Make sure the brake line is not stretched or damaged.

  • Remove the brake rotor from the wheel hub.

  • Remove the bolts retaining the hub/bearing assembly to the knuckle, then carefully pull the assembly from the splined end of the halfshaft. If available, use J-28733-A or B, or an equivalent spindle remover to prevent damage to the shaft or hub/bearing assembly.


  • Remove the cotter pin from the drive axle end nut and retainer


    Remove the retainer for access to the end nut


    Loosen the drive axle nut-here the caliper is installed so a drift could be inserted to keep the disc from spinning

    I need a diagram on f250 hd 4x4 front wheel bearing to replace them


    1 Jack the front of the vehicle up and support with jack stands. Remove the front tires and the front brake calipers. Hang the calipers up or support them so they are not hanging by the brake hose, which could damage the hose.

    2 Remove the caliper support, then remove the center bearing cover using the hammer and chisel. Tap it out easily so as not to bend it. Remove the cotter pin in the spindle.

    3 Remove the large bearing retaining nut and grab the rotor with your hand and rock it forward just enough for the front bearing to fall out.

    4 Put the large bearing retaining nut back on, but do not turn more than four or five threads. Grab the rotor with both hands at the 3 o'clock and the 9 o'clock position and pushing down slightly, pull the rotor off swiftly. This will remove the rear bearing and seal at the same time. The retaining nut will knock the bearing and seal out as you pull the rotor off. Remove the retaining nut.

    5 Remove the inner races for the bearings using the hammer and chisel. Put the chisel on the top of the bearing race and hammer it down toward the floor and then turn the rotor over and do the other side the same way.

    6 Install the new bearing races using the old races as a buffer or an installing tool. Lay the new race in the rotor and line it up to the recession and lay the old race upside down on the new one. Hit the old bearing with the hammer to drive the new bearing into the recess. Make sure you drive the new bearing all the way into its recess. Do the same for the other side.

    7 Fill the palm of your hand with grease and push one bearing at a time into the grease and drag it across the hand so that the bearings get a full packing of grease. Install the large bearing first by dropping the bearing into it's race and then installing the seal with the hammer.

    8 Install the rotor back onto spindle and hold it in place. While holding the rotor on the spindle with one hand install the front small wheel bearing followed by the large washer and the retaining nut. Tighten the retaining nut (use the crescent wrench) just enough so that there is no play felt. Tighten the nut another 90 degrees with the wrench and then rotate the rotor a couple of times. Back the nut off until it is loose then tighten just until you feel the friction of it tightening up again and stop right there. The bearing must be tight enough that there is no freeplay, but not so tight that the bearings will seize up when they heat up and expand.

    9 Install the cotter pin and the bearing cup. Install the caliper support and the caliper. Do the other side the same way then install the tires.

    Need to replace right front wheel bearing


    Remove the wheel and tire ***'y. remove the brake caliper to get it out of your way, then take the dust cap off the rotor where you'l find a nut with acover and a cotterpin. remove the cotter pin, nut coverand loosen the nut, the rotor will come off. the outer bearing will immediately come out if ti's not buried into the race. Remove the inner bearing by knocking out the which you'll need to replace as well. actually to do the job right , replace both races, bearings and the seals. the races and bearings have to wear together and using new bearings on old races is just asking for trouble soon, as they do not wear together like they should. Pack bearings with new grease, install the new races, put some extra grease inside the rotor so the bearings and races will have plenty of lube, install the inner bearing then the seal, put the rotor on the spindle, install the outer bearing nuut, tighten the outer nut just until the rotor rotates one to two revolutions when spinning freehand andinstall the nut cover and the cotter pin, caliper wheel and tire, you're finished, good luck.

    Cant remove the rotor and retainer clip


    You will need a large bearing retaining nut socket (1-in drive) about 2 7/16th in or 61/62mm (I got mine at NAPA with a 1/2 in to 1-in drive converter) BUT BEFORE loosening the nut there is a small keeper under the bottom edge the nut at the top (12-oclock) position of the nut. Use a magnet to retrac this and then loosen the large bearing nut. You sometimes have to slightly move the nut "a hair" left or right to remove this bearing keeper. Once the keeper is out the nut will easily come off. The rest is easy. Good Luck!
