Question:

I’m interested in getting wheel bearings, tires, and perhaps a latch mechanism for an old Karavan jet ski trailer from about ‘96. I have taken photos that I can send if it is helpful.

Welcome back Ken! You can send any pictures you have directly to the email address you receive this response from. If you have a part number off of one of your hubs that would be extremely helpful.

If there's no part numbers on the hubs, what I'll need to find you replacement bearings is the size of the spindle. You can find this by looking for part numbers stamped on the sides of the bearings or you can measure your spindle with a digital caliper like item # PTW80157. I'll need the C and D dimensions shown in the diagram below.

Additionally, I am also going to need to know your lug nut pattern so you do not have to change wheels. I have linked an FAQ below that'll show you how to measure them. With a trailer from 1996 you may get a strange lug nut pattern so I find it best to verify.

If you could give me some more details about what kind of latch mechanism you're needing to replace, I can look into that as well.

What style of wheels are you looking for and what size tires?
