It sounds like your assemblies are not the typical assemblies and will need to be replaced. For your brake assemblies, I recommend the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA along with mounting hardware # BRKH12. If you don't have the brake flange compatible, you can use the Brake Mounting Flange for 3" Round Axle # 4-44-1 which needs to be precisely welded in place.

Then for your drum brake assemblies to match, I need some more information. I will need either the numbers on your current inner and outer bearings and seal off one hub or I will need some spindle measurements. If you measure the spindles in the bearing locations and the seal locations using a digital caliper like # PTW80157 then I can use those precise measurements to help find the replacement bearings and hubs needed.

I've attached a photo to assist.

This is a good news/bad news situation. We don't have a hub that will fit the bearing sizes you need for your spindle. If your hub will work with the new brake assemblies, then we have the replacement bearings and seal. The bearings are # 2788, # 1779, and the seal is most likely # 29031 which has an inner diameter of 1.875 inches. If the hubs do not work with the newer brake assemblies, then you will need to replace your axles to get a modern fit as the part 22834 hub that you would need has been discontinued. If you want to replace your axle, I recommend the Timbren Axle-Less Trailer Suspension System with Electric Brake Hubs - Straight Spindle - 3,500 lbs # A35RS545E which will also replace your suspension components. This requires a 2 inch square bar (not included) to use in the integrated holes of the assemblies. I've attached a couple videos to assist. If you are desiring a more traditional axle, we have the 95 inch # 7359765-EB with the 80 inch center on center spring seats or the 89 inch long # e43SR with the 74 inch center on center spring seats.

The reason your trailer is heavily leaning to one side is because of the way it's loaded. From the picture, it appears that you have much more equipment on the right side than you do the left side. This uneven loading has caused the leaf spring…

So after quite a bit of research it seems that the Trostel 300-156-6 seals you mentioned are quite old and have not been around for some time. The best I could find was that they are 3.00" in outer diameter, and I did manage to find a customer…
