Surge Drum Brake Actuator Solution for Older Trailer that has 4 inch Wide Frame

Question:

I recently acquired a 1973 AVSE car hauler trailer. I’m fixing it up but have run into two problems. The first is I’m trying to repack the wheel bearings but the grease seals have started to disintegrate and I can’t seem to find any replacements. They are stamped Garlock 21660-8258 and the outside dimension is 3 inches. The second issue is that the hydraulic drum brake actuator is leaking brake fluid and really needs to be replaced. The problem is that the trailer tongue is 4 inches wide but the industry standard appears to be 3 inches. I have been unable to locate actuator that will fit this trailer. Any help would be greatly appreciated

I googled the grease seal number you mentioned and I did find some options online but when I looked up the size it wasn't one that we carry a suitable replacement for.

For a coupler solution though you could use the Dexter part # T1607500 which you'd want to weld to the top of your trailer frame. It was not designed to fit over a frame channel so your width being wider than usual wouldn't be a factor.
