i myself just gone through almost a gallon..and already the conrod need to be replace.....as for the bearing i don't see anything...
but if u have doubts u better change the bearing... 
detonation is what kills the conrod. If the compressed mixture fires too early then the explosion creates the downforce before the piston reaches TDC thus pushing down on the piston and rod while inertia keeps the piston coming up the bore.
