It sounds exactly like what I had. The way I determined which end had the problem was by removing both roller and gear assemblies. Mine was on the rear (drive end). After you remove the pin (actually a 1/4" bolt) you can turn the shaft with a wrench to extend the other end completely. It's very unlikely that the 1/4" bolt will shear since I don't think it is the weak link in the whole assembly.
