Finally found a center section with 4.11 gears! Tore it down to rebuild and inspect only to find some wear on the shoulder of the small pinion bearing housing. It looks like the outside races might have wore into the shoulder. Not a whole lot of evidence of the race turning though, oddly enough. Picture should be attached. Anyone see this before? Considering using another housing and putting my gears into it.

Thanks!
