How to Determine if Trailer Idler Hub Will Fit on Karavan Boat Trailer  


I would like to replace the hubs and bearings on my Karavan B245074 Boat Trailer for a Seadoo Challenger 180. Would the “Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 4-1/2 - Galvanized” be right for this application?


Expert Reply:

I wasn't able to find specs on your Karavan trailer but you can easily confirm whether the Trailer Idler Hub Assembly # AKIHUB-545-35-G-EZ-K will fit by pulling your hub and checking what your bearing and grease seal part numbers are:

Inner Bearing - # L68149 (1.378" inner diameter)
Outer Bearing - # L44649 (1.063" inner diameter)
Grease Seal - # 58846 (1.719" inner diameter and 2.565" outer diameter)

Attached is a review video for you to check out.
