If its a tandem axle trailer, there won't be any difference in weights on the axles, no matter how its loaded.
That is how tandem axles are designed IF they are working properly. When I re-did my suspension last year I found the equalizer link frozen from rust and unable to move and do any equalizing...
Also this assumes that the trailer is being towed level...if the TT is not level, then the axle on the low end is carrying more weight.
Also consider that shooting the hob with an IR thermometer at a rest stop is pretty inexact. You are not really getting the true bearing temp, but more the rim temp, which is some combo of tire, brake, and hub temps.
If you shot those temps right after pulling into a rest stop, it's possible that the rear brakes are adjusted tighter than the front and created more heat by doing more braking work. Also check tire pressure, lower pressure in the rears will make them run hotter.
Bottom line you can only blame the heat on the hubs after you have ruled out tires, brakes, and suspension.
