Reply to "Pinion Question"

Guy's,
This is what a pinion looks like when its' useful life is coming to an end. This tooth is beginning to break down the surface heat treating performed when new. ALL ZF pinions do this and I've seen many with much more severe a breakdown.
It may last ten years with light use or completely fail next week........ but it will continue to shed material and accelerate the wear of other components, especially all of those needle & roller bearings in the transaxle which do not come cheap besides the labor to get to them.
You can roll the dice or as suggested by Jack, now is the time to decide on another ratio or stock replacement ratio.
Hope this helps ! !
