Any tips on welding that tube to the top of the differential? I don't have nickel rod, tried heating up the diff (don't think I did enough) and welded a pretty good bead where my tube hits my diff. Put a little heat on it after the weld to control the cooling and pinged the bead pretty good...but this evening when I came home it had cracked.
The housing is cast steel so just need to run good hot bead on no special prep or post heating is needed. That is only for cast iron. You will need a plate in between the tube and axle tube to keep it from flexing and breaking the weld.
