Determining Replacement Hubs For Older Long Boat Trailer

Question:

I am looking for replacement hubs for my older Long boat trailer. The hubs are a 5 stud on a 6 1/2 diameter hub. I love my wheels and do not want to switch to a 6 stud. Please advise. David

I would be more than happy to recommend the correct replacement hubs for your older boat trailer but first I will need to know the inner and outer bearing numbers or measurements, and if the bolt pattern on your wheels is 5 on 4 1/2" or 5 on 5 1/2".

Starting with the bearings you will need to pull one of the hubs and look for the numbers stamped on the side of the inner and outer bearing like # L44649. Since you mentioned that the trailer is older the bearing numbers may be unreadable in which case you will need to use a digital calipers like # PTW80157 to precisely measure your spindles for the C, and D measurement shown in the diagram I included.

For measuring the bolt pattern on your wheels I have included a helpful article that will walk you through the measurement process.

With the bearing numbers or measurements, and wheel bolt pattern I will be able to recommend the replacement hubs you are looking for.
