Q: How to Maintain an 8-Stud Wheel Hub on 2000 Dodge Ram 3500?
A: For 8 stud hubs, first lift and steady the vehicle and then take off the wheel and tire assembly. After that, loosen and detach the nuts attaching the hub extension to the rotor, unless the model is a DriveLite without this part. Take out the brake caliper and afterwards undo the cotter pin and hub nut from the axle shaft. Detach the ABS wheel speed sensor wire from under the hood and take out the entire sensor wire from the frame and steering knuckle if you have one. Turn all the bearing/hub mounting bolts by a quarter inch backwards, then tap them with a hammer to loosen the hub/bearing from the steering knuckle. Undo the bolts that hold the hub/bearing on and remove the hub/bearing with a pull. Then, come out the rotor assembly, brake shield and spacer from the steering knuckle. Press back the wheel studs or hub extension studs, remove the rotor from the front hub and disconnect the wheel speed sensor from the hub bearing if you see one. If your hub bearing is present, secure the wheel speed sensor first onto it before installing the rotor on the hub or bearing. Insert the studs/extension studs from the back of the rotor, through the hub bearing flange all the way to the other side. Ample anti-seize material should be applied to all the front drive shaft splines. Insert the back, top and bottom hub bolts of the two rear rotors into the steering knuckle's top so their shafts run out the front end. Install the hub spacer and brake shield on the bolts in the knuckle, making sure if the vehicle comes with a wheel speed sensor, the brake shield is on the hub bearing. Place the rotor hub against the drive shaft and push it into the splines, putting the wheel speed sensor wire on top of the knuckle, if available. Put the bolt holes on the hub bearing flange into line with the bolts on the knuckle, then thread the bolts until the assembly is slightly tight. After the bearings are set, continue by putting in the remaining bolts and tightening the hub/bearing bolts to 166 Nm (122 ft. lbs.). After the washer and hub nut are in place, tighten them to 245 Nm (180 ft. lbs.), add a new cotter pin to the nut and adjust the nut to bring the hole in the shaft and the hole in the nut into alignment. After replacing the brake pad, put the caliper back, add the sensor wire to the steering knuckle and frame if you have one and mount the wheel speed sensor wire where needed under the hood. Should the car require it, attach the hub extension and nut, tighten them to 115 Nm (85 ft. lbs.) and then attach the wheel and tire assembly again. When you're finished, remove the support, drop the truck and apply the brakes a few times to set the shoes and caliper. Do not move the vehicle until the brakes feel secure.
