I ain't Flip,
but I'm skip, and I'll answer ya.
When mine went out it sounded like a rear brake dragging.
Mines an '07 too and had it 6 weeks from new,
at least new to me,
it was a demo back then,
anyway it took 6 weeks for the part to come in,
but Triumph replaced the entire rearend assembly at no cost.
Them, standing by their product,
is why I bought my wife a rocket last year.
Good luck with yours.
