Hi All!
Just to clarify, this guy was using a dual case crossmember with only a single case and mount. That puts a lot of stress way out on the tail, where the second case normally is bolted to. Since nothing was out there to support it, and it hangs lower than the rest of the crossmember due to the drivetrain slope, the rear twisted upward on impact.
Perhaps the original poster could change the title to say that his friend failed to put the second case in!
BTW, the tcase damage was internal stuff, NOT related to a bent crossmember!
And we form them cold like everyone else. Heating steel to bend it is a great way to weaken it.
Hot rolling is used to manufacture the steel, not parts. Cold rolled plate is not available and would be VERY nasty due to all that flaking scale.
See ya out there!
Bud
