  Q: How to service front wheel bearings on Ford Explorer Sport Trac?

  A:

  You should inspect front wheel bearings only while you lift the car for brake pad changes. Either way, they need attention when the front of your car goes up. There are specific tools you need for this job: a torque wrench and special grease. Begin by first lifting the vehicle on jack stands, then check the wheel with three main tests - listening for noise while spinning, noting how hard it takes to spin, and looking for unexpected movement when you push and pull the wheel. Before lifting your vehicle, turn off the Automatic Ride Control air suspension switch to avoid harming the car. Mark pressure the wheel, and when you feel movement, it's time to check and maybe fix your hub bearings with grease or new bearings. Take off the wheel and brake caliper, being careful not to let the caliper hang through its rubber connection. After 1995, take out the mount for the brake caliper when you replace it. Pull the cap off first, remove the straightened cotter pin, and throw it away. Take the retainer, its adjusting nut, and flat washer off the spindle. Give the hub assembly a gentle bump forward, then push it all the way back to break free the outer bearing. Started by sliding the hub off the bearing post. Insert a flat metal bar underneath the hub to lift the seal taking care to remember the seal's insertion location off the backside. Clean the wheel bearings and hub by dissolving grease with solvent, allowing every part to air dry without rinsing. Check the bearings for cracks, look for discoloration from too much heat, and see if they show signs of wear; you also need to check if the races are damaged; if any races are defective, replacements must be done by a professional. Put in plenty of high-temperature grease for front wheel bearings, work it thoroughly within both bearings. Snip a thin layer of grease onto the spindle. Spread a tiny amount of grease inside both bearings' raceways within the hub. Place the hub on the axle, push the greasy inner bearing into place, add more grease, and put a new seal covering it, pressing it down to match the surface. Line up the hub assembly over the spindle, use a small push to place the thickly-lubricated outer bearing where it belongs, and fasten the flat and adjustment nuts loosely on top. Position the hub and turn it around to let the bearings get the right placement and clean up any extra grease or sharp edges. While spinning the wheel, increase tightening on the nut until it reaches its correct torque, then screw it back off half a turn. Screw the nut tight again to the recommended torque level. Add a new cotter pin, then adjust the retainer so its holes match up. Before trimming, press down the two cotter pin ends to flatten them against the nut. After putting in place the cap filled with grease, attach the caliper, and lock the wheel onto the hub with lug nuts, tightening them until they reach the right torque. After that, make sure to follow the same bearing inspection steps and lower the car.
