Were the trucks made in the Silao plant any different in quality? Specifically, I am looking at a 99 k2500 suburban that was made in Silao. I know the newer trucks made there have less tight tolerances on some of the machining, making things like differentials wear out faster. Has anybody had any issues with a truck from Silao that they would have not have had on one from Janesville or Fort Wayne? Specifically on trucks from the 90's.
