WOW, today was very expensive. Just melted a 2nd center diff! I picked up some Traxxas 500,000 oil and put it in my new one, that's the highest my LHS had. I checked the temperature and it was 268F!!! The motor was only 153. The gears started grinding again. I opened it up and the oil looked like black tar. Nothing is binding, the bearings are new.
1. Who carries 2,000,000 diff oil? Link? Anyone in the US? I see LMI Racing does but I can't read their website.
2. Who all makes aluminum differential cases?
