I was at Award Diff dropping off my broken truck and on the bench was a transfer case out of a 79 series. The owner complained that he wasn't able to engage low range. If anyone is unsure what prolonged mixing of oil and water manifests into, here you go.



If i had thoughts that my routine of 6 monthly oil changes was overkill this alleviates my concerns that $30 every 6 months is money well spent.
