Joe;

Many thanks for the suggestions!

: Your machine may be symetric, but your driving may not be. Your drivers may prefer to operate your machine in a method that stresses one motor/gearbox more than another.

We will definitely look at this in FL.

: Alternately, it could be that the electical lines on one side are longer or have other losses the other does not, thus protecting one slightly from the full stall forces.

Nah, already check this part.

: Yet another factor could be that even though you machine is symetric, the gearboxes themselves are not. Specifically, perhaps the asymetry puts more plastic in the load path during its worst case loading. This more plastic could either be protecting the failure mode or adding to the failure mode. Either way, one side fails consistently before the other.

Now that sounds interesting indeed. Can't wait to get to EPCOT to check!
