I think you're onto something red.  My dad showed me that video and was saying it seemed like an issue of harmonics, like at that particular speed it caused a bad harmonics issue with the toyota, but like you said it could have also had something to do with them removing the reciever and some ridgidity.

Either way, like has already been said toyota will back up their products like few other manufacturers, and in a way the big 3 could learn from.  Toyota sets the bar extremely low for recalls, sometimes under 10!  When they recalled the last style of tundras/sequoias for the spindles they'd had less than 10 failures but wanted to cover their bases.  How many fords burned up while ford refused to admit they had wiring issues?  A non driving, non running truck in a driveway should NEVER ignite it's own fire.
