Exclamation Gear help

So I have a 2005 5.4 v8 Gibson headers k&n superchip no cats with 4.88 gears .

Recently raced on the frywy and once I hit 100mph my rear tranny yoke and trans casing cracked . Hand bad ujoints and out of balance drive shaft .
For replaced trans and u joints and balanced drive shaft but at 85 I still get a rattle. The same rattle that if I would go 90 then 100 it would get worse and most likely blow up again.
I'm trying to figure out the issue. Any ideas? I'm thinking the pinion angle is to low when they installed my gears and that's what's causing it or my aluminum driveshaft is just plain junk
