Wow I'm surprised you were able to weld on that cast iron.


Easy, steering arms are made of forged steel, not cast iron. Aside from the engine block, exhaust manifold(s) and EGR valve, I don't think there is any other cast iron on the Toyota trucks. Easy to check for iron or steel with a grinder. Just touch the grinding wheel to the material and if you get dull red sparks, it is cast iron, if you get bright orange/yellow sparks, it is steel.
