Uneven Bearing Temp
I have run into a situation that I have not seen before. The bearings on the rear axles are about 30-40 degrees warmer than the front axles using temperature gun. I have pulled the bearings and no pro...

Understanding temperature is so important for so many things in industry. Measuring bearing temps is huge in a factory. Load balance is one issue the can sway the temperatures of bearings doing the same job. As almost everyone has said, this could easily be caused by the trailer traveling not level. You are putting more stress on the rear wheel bearings over the front wheel bearings. The only unknown item, what temp can the bearings handle. It might be well within their tolerance and not an issue, or it could be outside of their tolerance and you are prematurely causing a failure. Sorry, I don't have any knowledge of what temps trailer bearings can run at. But a simple solution seems to be to find a way to get the trailer to ride level.
We did an experiment looking at semi truck and trailer brakes and bearing temps. What we found is that all manufacturers have a different tolerance to temp and we could not use a standard to determine if they might fail. The only temp we could use was the lack of temp - a failed brake or bearing has no temp (or just ambient temp) so that was failed. We were working with the LEO's so they pulled over trucks with failed brakes and made them fix them before returning to the road.
