To pick out bearings/seal for a trailer hub you will need to remove one of the hubs so that you can remove the bearings and get the numbers off of them.

Or, you can measure the spindle where the bearings/seal ride so that we can pick you out the correct bearings that would fit the spindle. For the seal we need to know the outer diameter of the spindle where the seal rides and the inner diameter of the hub where the seal fits.
