Trailer Wheel Bearing Issue

[63corvette]

A quick update on the trailer bearing issue.
The son was found to have a brain tumor the first of October with two surgeries to follow that my racing was done after the trip to Topeka for 2017.
I have now pulled all the China bearings out of the 2 remaining axles and all axles now have fresh grease and new USA Timkin bearings.
There were a couple of the China bearings I pulled that looked discolored. Not rough in any way just like they were etched in a few places. They are now trash anyway.
The next racing trip will now be in February or March 2018 and I will take the temps and post again how it goes for everyone to view.
I really believe with a better balance front to back and side to side in the trailer and the bearings change will take care of my issues.
My personal idea is that the balance of a trailer weight over all the axles is more important than I had previously thought. I thought in the past the three axles balanced the weight themselves better than I do at this point.
Again thanks to everyone for the input.
