Well, so much for going 4 wheelin yesterday.... broken driveshaft

[WORKIN]

Actually, the aluminum looks different because it's gaulded (sp?) The driveshaft tube spun around the yoke before it came apart.[/quote]



correct me if i'm wrong, but the yoke appears to be cast, and the tube i assume is not. so the aluminum's properties are different which accounts for the difficulty in welding, my wife manufactures aircraft engine fins for ge and they have the same problem.
