I have a 2015 Karavan Trailer, Model No. BW-2450-74-ST, and wanted to get a trailer hub assembly to fit it. It has a 5 on 4-1/2 bolt pattern, single axel, GVWR 2945, load weight 2450, ST185/80D13C tires, 13x4.5 rims. Thank you in advance for any help you can provide.

Hello R K,
I do not have a database that supplies me with what is put on what trailers. In my search, I see that the Karavan Trailer, Model No. BW-2450-74-ST should be equipped with bearing numbers: inner bearing L68149 (1 3/8"), and outer bearing L44649 (1 1/16"), you will want to double check your bearings, or measure your spindle to make sure the measurements are correct (I included an image that shows where to measure). If you see an axle tag on the axle and it is rated for 3,500 pounds, no need to measure the bearings I mentioned will be correct.
With that being said, if it all matches up you will want the Easy Grease Trailer Idler Hub Assembly for 3.5K Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-35-G-EZ-K, galvanized hubs are great for marine applications.

Hey R K, did the Easy Grease trailer hub assembly end up fitting your Karavan trailer once you checked the bearing sizes? Knowing how the measurements lined up could really help others with the same model. Your update could make it easier for the next person trying to match their hub.
