How do you replace the rotors on a 1990 ford bronco?

Answer 1

you have to remove the hubs pull the rotors transfer the bearing races and reassemble Make it easy on yourself, buy rotors with races already installed. Most will have them. You'll need an inch pound wrench (or do it be feel)for reuse of old bearings, and a foot pound for new bearings. You'll also need the spindle nut spanner socket, snap ring pliers, a pick, hammer, and punch. The punch will have to be slightly smaller that the diamter of your lug nut studs. If you're lucky, your spindle nut will be the newer ratcheting version which I believe does not need to be torqued. The older setup had two nuts, one with a pin, and a washer between them that required alignment with both the pin and inner groves of the hub. Your's should have the new nut. First remove the lockout assembly. This will expose a snap ring on the axle shaft and an inner snap ring inside the end portion of the inner hub. Remove them both. Next use the spanner to remove the spindle nut(s). Pull the hub and rotor assembly off of the spindle. Be careful not to allow the outer wheel bearing to fall out and onto the ground. It may become damaged. The seal will keep the inner bearing from falling. After you get the bearings and seal out of the rotor you'll have to separate them. This is done by using the punch and hammer. Just set the punch on the end of the studs and pound away until they're out. Be mindful of the threads, or just replace the studs with new ones and you won't need the punch. The studs are cheap enough. Next, remove the seal and inner bearing. After that, put the hub on the new rotor and install the studs. Just set the hub end on a piece of wood to prevent damage and pound the studs in from behind. You'll seat them later when you put the wheel on. Again, use a foot pound wrench. After you have the hub and rotor together, pack your wheel bearings with high temp wheel bearing grease. This is difficult to explain, but there is a simple technique. Put a blob of grease in your palm and scoop in with the wider edge of the bearing. If you're doing it correctly, the grease will be forced through the bearing you'll see it come out of the smaller end. Rotate the bearing and repeat. After you have the bearings packed, install the inner (Larger) bearing and then a new seal. Lightly coat the spindle with grease. Put the rotor assembly on the spindle and install the outer bearing as squarely as possible. Install spindle nut and replace the lockout assemble. Put on the wheel and seat the studs. Keep everything clean, take your time, and use good parts. If you have the two nut spindle setup, put the nut with the pin on first with the pin facing out, install the washer. You may have to tighten or loosen the inner nut to line up the pin. After that, install the outer nut.
