It certainly won't be those gears that fail. I have them in my muggy; the only part that seems to go is the bearings on the rear diff pinion. When that happens, the gears can slide by each other. If that happens with the stock gears, the teeth will chip. I had it happen with the TiNi gears and they were fine. I also learned the importance of quality bearings in the diffs.
