Yes, I forgot to mention that!
The issue does in fact lie in how the tensioner is mounted. Front tensioner in mounted to plastic, rear is mounted to motor mount. Combine the fact we run beastly motors now and not to mention a crappy bearing in the tentioners, its recipe for a weak link in the drive line.
It could even be possible that the bearing in the tensioner is creating some amount of heat that ends up transfering to the bearing shaft--> then to the mounting area of the tensioner which is... PLASTIC!!
Im just trying to look at it from all angles. I noticed that finding the right amount of tension on the belt is very important.
