I would like to help you. Your not giving us any information. Without any observations or attempt to diagnose the issue all anyone can do is guess whats wrong. You dont have to ask us if your bearing is hot. Feel the wheel and see if its hotter than the healthy side. The only sources of heat are brakes and bearings.

 

I had that problem of the cv boots bursting on track. I used a temp gun and saw everything was way hotter on the rear hubs. replaced wheel bearings, hubs, and just to be safe, the axles. no problems now!

 

I thought I would post the solution I found for my problem sometime ago. As alluded here by several - the culprit was bad bearing which was generating too much heat. Amazingly enough no one who worked on my car until I got lucky with one mechanic was able to diagnose issue. No play or noise was really produced but bearing was “fried”. Replaced hub and bearing and issue solved. From now on I will do this every few seasons as prophylactic measure for track dedicated car.
So - if your boot is tearing/blowing up - check the bearing/hub even if no play or noise.
