Well, the feigao got very hot one run, like 300f, so its back to the 1518. I have been driving as much as I can with the varying weather around here. Managed to blow the rear diff again.
FIX: I have ordered two spider diffs for front and rear, along with matching pinions, shims and also 20mm big bore dampers with hard springs. This truck is going to be a tank!
