How can i do Front wheel bearing replacement 98 Mazda b2500?

Answer 1

It isn't a hard job to do. first thing is to lift the front tires clear of the ground and secure the truck with approved safety stands. Remove the wheel. Take the brake caliper loose. It will have a bolt and pins holding it in. While your this far you may want to replace the brake pads. Ten bucks now will save you the job later. Pop the dust cap off the hub and remove the cotter pin. Unscrew the nut and remove the cap on the nut if it has it. The hub should slip loose and the outer bearing will need to come out. Place the nut back on the spindle. Screw it on just until it's flush with the end of the spindle. Now the tricky part. Grab the rotor with both hands and snatch it off while letting the seal and bearing catch on the spindle nut. If you do it right, the inner bearing and seal will stay on the nut and the hub is now in your hands. If you are replacing the cups as well as the cones, you will have to drive them out of the hub with a race driver. the new parts will drive in place and you'll need to grease the new bearings very well. Packing bearings is an art. They make a tool to do it and if you've never done it before, it would be worth the money. Pack the bearings and grease the inside of the hub and slip it all together like it came apart. When you get it all together, screw the nuy back on. You now have to set your bearing preload. Turn the nut by hand until it's snug. Use a wrench and tighten it a little more to seat them. Back it off and snug it by hand again until there is no slack in the hub. tighten it just until it lines up with the next alignment hole in the spindle. Replace the cotter pin with a new one and put it back together. That's all there is to it.
