Wheel bearings ensure that wheels turns correctly and smoothly, and if the bearings are going out on your vehicle, you'll generally hear the noise. If the problem isn't repaired before it gets worse, the bearings could seize, the wheel will lock and an accident could result.
Lift the vehicle into the air with the jack and support the frame on jack stands. Make sure the vehicle is secure before you crawl underneath it.
Remove the front wheels using the tire iron. Place them to the side so they're not in the way.
Unbolt the brake caliper from the spindle using the 1/2-inch ratchet and sockets. Then lift the caliper off the rotor and hang it from the wire hook so you don't put too much pressure on the brake line.
Unbolt the rotor from the spindle using the 1/2-inch ratchet and sockets. Keep track of the washers that go over the bearing, so when you reassemble the front end you put it together correctly.
Pull the rotor off of the spindle and place it face down on the floor. Use the seal puller to pull out the wheel seal from the rear of the rotor.
Pull out the rear wheel bearing and discard.
Place a handful of wheel bearing grease in your hand and work the bearing through the grease. Push the grease through the bearings so that it works all sides of each individual bearing.
Place the wheel bearing into the rear of the rotor and tap the replacement wheel seal into the rotor using the rubber mallet.
Place the rotor back onto the spindle.
Lubricate the front wheel bearing using the same procedure as you followed in step 7, and then place it onto the rotor. Place the washer back in place as well.
Tighten the nut back onto the spindle using the 1/2-inch ratchet and sockets until it's tight all the way, then back it off 1/4 turn so the rotor can spin around freely.
Reassemble the caliper and front end in the reverse order of disassembly.
