First, to remove the seal, turn the hub over with the wheel studs facing up on a hollow cinder block or on a couple of 2x4s. You will need to remove the seal by using a 1" wood dowel rod or scrap lumber that will fit into the center of the hub. Place the dowel rod against the inner bearing and knock out the bearing with a mallet in a circular motion. The wood will force the seal out without nicking the bearing or race. Be careful not to damage the hub and race when prying it out.

The best way to find a replacement seal is to look at the numbers stamped in the rubber part of the seal. You can also measure the inner and outer diameters on the seal which will tell you the seal you will need. Please note, these directions are only for trailer tires, not for vehicle tires.
