It is likely that the Dexter Trailer Idler Hub Assembly # 34822545BX for 2K trailer axles will fit but you need to verify that your trailer uses # L44643 inner and outer bearings, and that your current grease seal has a 1.249" inner diameter.

You can verify this by removing your current hubs and locating the bearing part numbers or by using a digital caliper and measuring your spindle to the 3rd decimal (1.234 for example). Your spindle needs to measure 1" where the bearings ride and then the 1.249" where the seal rides. I have attached a photo you can reference for this.
