How to Select Replacement Hubs

Updated 09/28/2016 | Published 09/27/2016

Question:

I have a 2003 Mastercraft single-axle boat trailer and need a replacement hub assembly. I believe the existing hub was a Reliant brand and has the oil bath cover. The hub is a 6 hole pattern and there are two separate markings on the hub: H 1206 1682 I can send photos if necessary. Thanks!

Selection of replacement hubs requires you to know the axle weight rating, bolt pattern (there are both 6-on-6 and 6-on-5-1/2 bolt patterns) and the bearing numbers from the current hub.

You need to ensure the new hub has the required weight rating for the axle, the same bolt pattern as your wheels and the same bearings, which ensures the new hub will fit on your spindles. Once you confirm these bits of information you can use the linked page to check for a suitable hub.

To help you I have linked an article on determining wheel bolt patterns and a photo showing the typical appearance of bearing numbers. Just click on the filters on the linked page to select your required parameters.
