In order to find the correct bearings, you'll need to remove a hub and read the reference numbers off the inner and outer wheel bearings. If you cannot read the reference numbers, use a digital caliper and measure the inside diameter of the inner and outer bearing and the surface of the spindle where each bearing rides. I've provided you a diagram showing this. You'll also want to replace your grease seal. To determine which replacement seal is needed, you'd measure the inside diameter of the hub bore where the seal is installed as well as the diameter of the spindle where the seal rides. With these dimensions, I can recommend replacement grease seal bearings.
