Question:

Hello do y’all happen to have a guide on how to find the corresponding bearing to a hub? I just picked up an older trailer that’s a 5x4.75 bolt pattern. I haven’t removed the hub but know one side is shot, what measurements are needed in purchasing a new hub or bearings. Thanks!

I have a few options for you to help with identifying the bearings on your trailer. The first and easiest method would be to crawl under the trailer and look for the axle tag on the beam. This should give an axle capacity which we can then use to find the bearings based off industry standards. For example, a 3,500 lb axle uses L68149 and L44649 bearings like what comes with the Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axles part # BK2-100 or the Easy Grease Trailer Hub and Drum Assembly for 3.5K Axles part # AKHD-545-35-EZ-K. The other option would be to take the hubs off the trailer and either read the part numbers off the old bearings or measure them with a dial caliper to the nearest thousandth of an inch. I have attached an article that goes over this process in more detail.

I have also attached a few links with lists of our bearing and hub selection.
