How to Determine Replacement Axle for Boat Trailer

Question:

I have a boat trailer with a single mobile home axle and would like to convert to a standard hubs, wheels and tires. The mobile home tires are 14.5 and the overall diameter of the tire is 25inch + -. The bearing numbers are as follows: SKF BR25580, BR25520, LM67048, LM67010 and seal number: SKF 22532. I would like to purchase the hub kit and wheels. The overall tire size could be up to 26inch in diameter and I would like to use as large of a tire as I can. Please quote me on the this conversion and if you sell the tires the price on those also. Thank you for your help!

Unfortunately the only option you have is to replace the entire axle. The reason for this is mobile home axles are designed for a single use, to get the mobile home from point A to point B and is not intended for any other purpose so it very important you replace that axle. From there you can convert to a tire that is as large as you have room for and that fits on your wheel and hub.

In order to choose the correct replacement axle you will need to know the dimensions of your current axle's hub-face to hub-face and spring center to spring center as in the diagram I have added; the other thing you will need to know is the weight capacity of the axle you need, which should exceed the GVWR of your trailer.

I've added a link to our selection of axles for you to check out, or if you get back to me with that information I'd be happy to try and find something that will work for you.
