Hey Paul thanks for the information but there is no database that shows me part numbers for your 2018 Karavan 2 place jet ski trailer. To determine the correct replacement idler hubs you will need to determine the bearing combination your spindle uses.
The easiest way to do this is by removing one of your current hubs and looking for the bearing numbers stamped in the face of both the inner and outer bearings as shown in the included picture of the item # L44649 bearing.
If your bearings are worn to the point that you cannot read the bearing numbers you will need to use a digital caliper like item # PTW80157 to precisely measure your spindles in the locations shown in the included diagram.
If you could get this information for me and leave it in the comment box below, I'll be happy to find you the correct replacement hub.

Thank you for getting back. The hub itself says KNOTT 17A01 6B7456 H. The outer bearing is a L44649. The inner seal says TRP 201702 GS-1719DL. The inner bearing is covered by the seal so let me know if I need to tear it apart to see the inner bearing part#. The inner bearing is bigger than the outer.
