I welded new caliper mounting brackets to an axle before. no problems at all.

Don't know if it was right or wrong, but I put a wet rag around the tube on the "back side" of where I was welding, to help keep things cool. I placed the rag on, THEN started to weld, so the metal never got "shocked" it did get hot and was hissing the water out of the rag, but I THINK it helped keep heat down on the axle tube itself.


Right or wrong, I put 4,000 miles on that axle with my big block Dakota without any problems, and my buddy is running it in his 318, T-56 Dakota that's his daily driver and has probably 10K miles on it since we put the axle in it last spring.
