The tubes are welded or pinned into
place, they are not supposed to move.
you need to have the knuckles re indexed
to the new rotation of the axle, about 6* is
where they should be, 5* would work also.
A friend of mine did this on a Dana 44, had to
grind the crap out of the welds and move the
knuckle, then reweld, moved at the knuckle not
the tube.
This can be done by Currie (sp) for about $250
I think, seemed cheep enough to me.
