Welding Tips and Tricks

? I am working on rotating the steering nuckles on a dana 60. I have some high content nickel rod from lincoln that has worked well for me on cast. I have a good bit of build up to do in some areas and would prefure to run wire feed. Is anyone familiar with this process, and if so could you recomend a good wire? Also while were on it does anyone know what kind of cast is used for nuckles and differentials, what temps for pre and post heating so on?

Forgot to ask: Lincoln had broblems with NR211 being brittle and came out with NR212, which is a more ductile filler. Anyone had experience with using this on cast?

Sorry I have never try this, but if I get some information I will provide you at here.
