Just got a d44 rear axle, should I weld the tubes to the housing? My in shop expert welder said to do it I should heat up the area to 350degrees use 5/32nd stainless rod, maintain 350, then wrap it in a heat blanket for a slow cool. But is there a reason, do the tubes have a habit of spinning in there? I'm only going 4.5" lift w/33" 10.5s
