It sounds like the seals have failed and the grease from the bearings has come out during travel. Also it is possible that if you have an EZ lube axle with a grease zerk at the end to add grease but use a single lip seal, the pressure can blow out the single lip seal.

If you have mixed incompatible greases they can break down and could some how evacuate the hub.

You will want to inspect the seals on the trailers to see if they are the issue. I can tell you what replacement seals you would need if you can tell me what the inner and outer bearing numbers are for each trailer.

If all three trailers have hydraulic brakes then it may be brake fluid you are seeing, If this is the case you would need to replace the wheel cylinders on the trailers.

I have linked a video on removing, inspecting, and installing bearings, races, and seals for you.
