Hi Ed,
There unfortunately isn't a guide to tell us what your trailer has on it so we'll have to check your current components for part numbers or measure the spindle and hub to find out what's going to fit. Since your trailer is newer we could probably look up the bearings and seals with the part number stamped into the face of the hub. If not, we'll need the part numbers from the bearing and seals.
If you have no visible part numbers then you can measure the bore hole of the hub for the outer diameter and points B, C, and D on the spindle from the diagram with a caliper # PTW80157.
