I am repairing a 2010 F-350 rear differential housing that lost the pinion and the pinion wedged its self between the ring gear and the bottom of the housing. The crack is 1" long and 1/8" wide. I am trying to figure out what the best procedure(clean, grind, preheat, weld, anneal, post heat) is to complete the task. I was provided with All Stated super 275 rod, but I want to be positive and only do it once.

I will be using a syncrowave 300 with a stinger in DC mode to weld. The material is about 1/8" thick where the damage is too the housing. it is bottom center of the housing.


Any help will be greatly appreciated.
Thank You
