To recommend the correct hub drum for your application, I would need to know a little more information.

First I will need to know your current hub bolt pattern. In order to determine your hub drum bolt pattern, you would need to measure center to center on bolts directly across from each other on the circle. If you have an odd number of bolts, measure from the center of any bolt to the point halfway between the two bolts directly across from it on the circle. The first number of your bolt pattern would be the number of bolts your hub has, and the second number would be the center to center diameter between them.

It would also be helpful to know your bearing's industry standard numbers. These are usually lasered onto the back side of the bearing. If you do not see a number, measure the inner and outer diameters of the seal with digit calipers to ensure accuracy.

Next I need to know the part number on your hub seal. You should find the numbers stamped in the rubber part of the seal. If you do not see any numbers, measure the inner and outer diameters of the seal with digit calipers to ensure accuracy.

Last I will need to know the axle weight rating. This information should appear on a sticker or a plate on the axle.

If you could provide me with this information, I would be glad to recommend the correct hub drum application for your needs.

If you take a look at the included link you can see a video demonstrating how to measure for the correct bolt pattern.
