Replacing Grease Trailer Hubs with Oil Bath Hubs

Question:

I have a duel axle boat trailer with disk brakes. Id like to replace the grease bearings with oil bath. The pattern is 6 lug on 5 1/2 inch diameter. I was wondering what hubs I needed to purchase in order to do this. The disks for the brakes slide on and are not part of the hub. Thanks.

Expert Reply:

You can convert some hubs from grease to oil bath using a kit such as # XLPROLUBE1980KIT but for others it would not be possible without changing the hubs. This is because oil bath hubs use an oil cap that threads onto the end of the hub. Most regular hubs are not threaded so you would not be able to screw on an oil cap.

If you can tell me the inner and outer bearing numbers on your existing hubs I can determine if there is a way to replace them with an oil bath system.
