How to Determine Trailer Hub Fit

Question:

I have the bearing out for an mobile home trailer Id like to convert over to the more stream lined version of trailer hubs. The front bearing number is LM67048 and the back bearing is JL69349. Is there a hub assembly that I can buy to fit?

Expert Reply:

There is a way for you to determine the hub you will need, although I was unable to find any type of reference to a JL69349 bearing.

That's okay because to find the right hub you can use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure.

Additionally, you need to know the weight rating of your axle and your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it.

I have also added a link to a help article on hubs and bearings for you to take a look at and have attached a link to our page with our selection of available hubs for you once you take those measurements. You can also get back to me with those measurements and I can see if there is anything available.
