Question:
I’m looking for a wheel hub kit for my 2022 SeaDoo Switch Compact Sport 13’ boat single axle, no brakes Karavan trailer. The VIN is 5KTBS1519NF678948. I found Drawing number 310-0347-A in the Karavan portal. However I can’t find any of the part numbers on your website. Also an assembled kit would be preferred rather than piecing it together. Can you help me with this?

Thanks for reaching out, Michael, and yes, I can help. I looked up the Karavan part number 310-0347-A and it appears this is a hub for a standard 3,500 lb axle. It uses the # L68149 (1.378" inner diameter) inner bearing and the # L44649 (1.063" inner diameter) outer bearing. They mention it is a 5 bolt hub, so I assume it is the standard 5 on 4-1/2" bolt pattern since the rest of the specs seem to be standard.
We do offer a great replacement for this hub, and for that I recommend the CE Smith Trailer Idler Hub Assembly # CE13515. This hub matches all of the specs I mentioned above, it comes pre-greased and it all comes in a convenient carrying case.
