Initially what you need to do is clean out all of the grease in your hub, on/in the bearings, and on the spindle. Once that is done you simply swap out the grease seal for the oil seal included in the Kodiak XL ProLube Kit # XLPROLUBE2440KIT (which has a 2.25" ID and 3.376" OD) and reinstall everything. You do need to make sure that the ID of the oil seal matches up with your current system so that it keeps your oil from leaking.

If you are needing to replace the bearings and seals as well then you should have a # 25580 inner bearing with race # 25520 and the outer bearing # 14125A with the race # 14276. You should be able to confirm that these are the correct replacements as the part numbers for the bearings should be visible when you remove and clean them.
