The best way to find the correct replacement bearings is to get the numbers stamped onto the metal of the inner and outer bearings that are currently on the trailer. With those you will be able to find the correct replacement bearings, races, and seals.

Another option is to measure the spindle of your trailer with a micrometer to get the diameter of it where the seal, inner, and outer bearings ride. See picture.I have included a link to a video on inspecting trailer bearings that should help you when removing the old bearings.

I have a 1985 Coleman Chesapeake pop up camper. I am trying to find the correct bearing seals for it. Thank you

I really wish I could track this information down, but the only way to determine this will be to pull one of your existing hubs and check for the bearing and seal numbers - they should be stamped right inside the bearings themselves. If you can tell me what you find I will be happy to make specific recommendations.

I have an 85 Chesapeake as well. Did new brakes and bearings and hub does not go on all the way used bearings l44649 ... because that's what came out of it. Not sure what's happening.. any suggestions?

@Corey Is the hub too long, or the bearings won't physically fit around the spindle like they are too small?

Reply from Corey

Everything is going on fine.. just not far enough for some reason. They are about half inch away from backing plate. And I cant get the nut in enough to get the Carter pin through. Had the races and bearings set by a garage to make sure they were in far enough.

@Corey Hmm that's interesting. Just checking on their work, is the grease seal at the back flush with the hub?

Reply from Corey

Yes flush with hub..

What would be the proper seal size.. I think the bearing kit that i purchased before i found you guys is to small.

@Corey The L44649 bearing kit # BK1-150 comes with a grease seal that has an inner diameter of 1.500". If you can measure your spindle where the grease seal rides with a digital caliper then we can verify what the correct seal is.
