Ahhh yes, I see you have them offset from the tires.  Should only be a case
of translating them to origin then rotating and translating back again, or
easier still rotate first then place them.

Since your car flies all that might be more than needed  ;-)

Yep, very difficult to watch.
Like I said, all you have to do is get the axles (axel is Middle English
apparently) on the origin <0,0,0> before rotating, as long as that step is
done and then they are translated to final position (unioned with car)
things should work as expected.

If you'd like to post that part of your animation script here it's easily
fixable if you can't get it right yourself.  But that's probably all you
need to know.  At least now you can also match the tires to the ground if
you wanted to do so... flat ground anyhow.
