Determining Which Replacement Brakes and Hubs Fit 1966 Frolic Camper

Question:

I recently purchased a 1966 Frolic Camper. The axle had electric brakes on it. When we purchased the camper, one of the wheels was seized by the brakes. I damaged the center hub and the bearing race while removing things, not to mention destroying the brakes. I think my best course of action is replacing the brake/hub assembly on both sides of the axle. I read something somewhere where you folks were able to find a compatible replacement based on some information. I know the following: The trailer weighs #1400 according to the title It is a 6 lug wheel that is considered 6 on 5 1/2 Where the backing plate bolts to the spindle of the axle there are four bolts. They are 4inch on the diagonal. they are 2 3/4inch Approximately across the top. They are 3inch across the other way. The bearing closest to you when you remove the dust cap, castle nut, and retaining ring is marked Koyo Japan 09067. The bearing at the spindle of the trailer axle is marked Koyo Japan 15123

Thanks for all of the pictures and measurements!

Based on the pictures of the braking assembly you have 10" diameter brakes with the the 4 bolt mounting pattern that is 2-7/8" apart. For compatible brakes we have the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K # 23-468-469.

Now when it comes the hubs we unfortunately do not have one that uses inner bearing # 15123 and outer bearing # 09067 so your best course of action will be replacing the bearings and races and reusing the hubs. For the inner bearing you will need bearing # 15123 and race # 15245, but we do not have any bearing or race that cross references with the 09067. I recommend measuring the inside and outside diameter of the bearing using digital calipers # PTW80157 so I can see if we have a compatible bearing.

If the hubs are not reusable then the only option will be a complete axle replacement. For this I recommend going with the Timbren Axle-Less Trailer Suspension System w Hubs - Straight Spindle # A35RS545, braking assemblies # 23-468-469 that I previously mentioned, and hub and drum assembly # 84656UC3-EZ which has the 6 on 5-1/2" bolt pattern you were looking for so you can reuse your current wheels.

This axle will bolt directly to the frame of your trailer and replaces the leaf springs on your trailer with progressive rate AEON main springs that do a much better job of absorbing road shock and will give you quite the upgrade in ride quality.

I included videos of the products mentioned for you to take a look at.
