Re: opinions wanted! welding spring perches
I gurantee if you set that axle on jacksands and put a dial indicator on the outside flange, then start welding youll see ALOT of movement at the end of the tube. Thats just the way it works.
clean it very well, grind it all clean, use brake cleaner..
position your perches, tack the 4 corners, then weld in SMALL maybe 1 inch increments, letting it cool in between.
if you look insde a factory axle you can see the heat lines, and the distortion of the tube by teh weld heat, but they MIGHT cut those outer bearing pockets after that process.
if you minimize the heat as best you can it should give you any problems.
I have seen guys weld 10 bolt and 12 bolt Chevy rears, Hi heat, singe pass on each siude and run them alot with no outer bearing failure.
but betetr safe than sorry.
