I bent the track rod just by hitting a curb and it sent the wheels all over the place. But it was a cheap britpart one.
If he's fitted HD stuff (depending on how HD that actually is) then I guess something else would break first.
I get mixed up with the names of the steering components but, I think, most of the rods would cause both wheels to go out of alignment IF the steering wheel was centered.
Whilst, it seems, that, with the wheel central, only one road wheel is on the wonk. Which doesn't seem possible with steering rods? I guess it might be if multiple rods have bent to compensate, but just one going would always offset both wheels if the steering was centered, wouldn't it?
