I'll start out by saying that bearing measurements should always be taken with a digital calipers like the # PTW80157, and will be measured down to the 1/100th of an inch (3 decimal spots). It looks like you've likely got inner bearing # LM67048 (1.250" inner diameter), but there aren't any outer bearings with a .875" inner diameter, so you'll want to make sure you've got an accurate measurement. You can also check the numbers stamped on the back of the bearings and find hubs that have matching bearings; you'll also need to use hubs with the same bolt pattern as your current hubs.

If you can let me know the inner diameter of your outer bearing, the axle capacity and your bolt pattern, I can help you locate the correct hubs for your trailer.
